I think showing the LENGTH of the rope you pulled with 2 pulleys v.s. 1 pulley will explain everything much better. It took me forever to finally understand. Maybe I am just an idiot. Edit: It's like going 10mph(force) for 2 hour(rope length) vs. going 10mph(force) for 1 hour (rope length). You get more out of it. That's how I understood it anyway.
I carry rope and carabiners while hunting to set up pulley systems to get large game up steep inclines. The input end also helps me climb up at the same time. Carabiners have much more friction, so they hold the load in place better.
Destin, You could have used a third scale, that would be holding the other end of the rope, the one that is fixed and does not move. Also, It is very interesting how the flatten unfolded multi pulley was not moving uniformly, indicating each disc excreted different force. It would be interesting if you replace it with separate pulleys each one holding separate weight (all weight would be with equal mass).
The guy that stopped to help you gave me a big smile too, hands weathered from what must have been a lifetime of physical labor gave and instantly knowing what to do, how to help and taking the time out of his day to stop for a stranger, very respectable and heartwarming.

A rule of thumb we always used for figuring out mechanical advantage for rope rescue systems was, if the pulley (or snatch block) is moving with the load, it is providing a mechanical advantage. If it is not moving with the load (i.e. it is attached to an anchor point not a part of the load) it is only providing a change of direction.
This is how I learned it when setting up a homemade lat pulldown in my gym. You don’t want the system to give you advantage you just want it to offer resistance in the desired direction. You also can’t afford having 2 to 1 ratios of distance. You want the weight to move 1 to 1 what your arms are doing. Otherwise you would have to double the weight to counter the advantage you’re getting. Gym equipment is, of course the opposite intention of many pulley hoisting applications.
Dustin... I just wanted you to know that I saved this video a year ago and have referred back to it often. This video is one of the finest examples of what makes your channel great. Entertaining, informative content that makes a person smile. You've really found you calling here and should be proud.
I noticed in the video when they pulled the jeep with the wench while it was in gear there was a blanket draped over the cable in an attempt to mitigate the force in the case that it actually did go down like that. Still a worthy note sir.
I seem to recall a video of Army engineers stepping ON the ropes of a multi-pulley setup if they had cause to traverse their setup. The reasoning being that if the rope did snap as it was crossed, the whiplash would be mediated.
I’m from Tennessee and I’ve noticed that everyone seems to do that. Is it like a subconscious peer pressure on how you should talk? I can’t figure it out.
After watching this video I was able to construct a pulley system with a 1300 watt winch and 6 snatch blocks that could pull medium size oak stumps out of the ground while preparing for a house build. Insanely satisfying to see the science work in real life. Thanks for this video. It saved me a lot of time and back ace.
Yes pulleys are amazing but always remember the safe working limit of your cable / line / rope / strop etc quickly becomes the governing factor. Great production by the way, makes learning stuff fun !
Shouldn't matter much, As you get more blocks in the load your line load reduces. If you have a 4:1 setup then your total load is divided by 4 and that's how much is on each line. So if you want to lift 1000 pounds a straight pull is of course 1000, a single traveling block causing a 2:1 pulley is 500 on each line as well as a 2:1 mechanical advantage so it both cuts the line load in half and doubles the pulling force, a 3:1 does the same its 3 times the pulling force and line load is cut into 3 so you are at 333 pounds per line. If you want to get real complicated you can factor in the angle at which each line is at and that chances the numbers as the farther from 90 degrees or parallel lines the less mechanical advantage and the less line reduction you have.
@@ionbusman2086 not really, with my 4:1 for example you are effectively turning 1 line into 4, so it’s really one long line that runs through a bunch of blocks but it acts as if there were 4 because both your mechanical advantage and line load are effected, for each moving block in a perfect world you get double the pulling force and line load is cut in half, so for a 4:1 moving 1000 pounds you would need to pull with 250 pounds of force and each line would have 250 pounds of force on it, so to move 1000 pounds a 250 pound rated rope would work. It’s fairly simple until you start getting into the angles of the blocks and compounded pulley setups. So yes in short the object weight doesn’t change you are still lifting 1000 pounds, but with pulleys you can move that weight with a lot weaker equipment and a lot less force.
@@ionbusman2086 what you are describing isn’t a proper mechanical advantage setup, to achieve mechanical advantage the blocks have to be on be load, if you have just one line actually attached to the load no matter how many blocks you have unless it’s a compound setup you don’t have mechanical advantage, for my 4:1 example you would have 2 snatch blocks on the actual load and 4 lines 2 for each block. What you could do if you could only attach one line to the load is have one heavy piece of rigging rating for the full forces then you could compound it and apply mechanical advantage to that one line, so like a 1000 pound cable sling with 250 lb rated rope in a 4:1 connected to that cable.
And what I admire the most that there are just so many sure signs that it's genuine! He approached random workers because they had a SNATCH BLOCK. Hahahaha!
Lol I’m from the Midwest west and I work for a company that does work all over the country and for whatever reason I start to talk like that when speaking with that southern accent on the phone. 🤣 no idea why lol. Same when I hang out with my hick friends 😆 I say creek but when hanging with them it turns into crick lol
I used to live in the super deep south, but I've since moved to the Midwest. Sometimes I catch my southern accent coming out when I generally don't speak with one.
My physics teacher had the same energy tbh! I wasn't great at physics but I took as much of it as I could because of him. Also he showed us Paul Hewitt physics vids!
Hey Destin, I bought some Snatch Blocks after this video came out (Same ones you used). Never used them but I got to today! We used a double snatch to lift up a heavy piece of furniture up some stairs. Only knew how to do it because of this video.
We do that literally all the time, I think the southern accents are fake because we only sound like that when talking to other Southerners. Also some won't take you seriously if you don't sound like that
Not kinda like gear ratios. Exactly like gear ratios. The only difference is the directions of the forces. And technically, since you most often think of gear ratio in terms of vehicular motion, even the directions are not that different. Input is the vertical movement of the piston head. Output is the force applied to the road. So a pulley can create a ratio and change the direction of a force. While a gear can create a ratio and reverse the rotational direction of a force.
@@codeman99-dev it's also exactly like a lever and fulcrum lol. The ratio between thee distance from the end to the fulcrum between both sides is the ratio of force increase. You sacrifice distance for force and since distance is proportional to speed, one side of the lever will move faster than the other. Instead of rpm you calculate the speed it takes for the end of the lever to go from top to bottom, since they both go top to bottom at same time but one goes a larger distance, there is a difference in speed. Plus change in direction, one side goes up, other side goes down. One gear spinsclockwise, other gear spins counter clockwise. When you think about it, a gear is just a lever spinning around its fulcrum, and pulleys are just gears connected with ropes. All types of mechanical advantages are the same concept really.
Hey Destin. I just used the "snatch block" technique with a come-along to get my tractor un-stuck from a pile of manure. THANK YOU for saving me from having to dig it out the poo! You really saved me.
I am a Mechanical Engineer who once did a similar demo on the power of pulleys in my kids' Science class, but yours was way better! Love your enthusiasm for the topic!
first, thank you. your willingness to share the power of knowledge is much appreciated. So, years ago, we had a tow truck (an old P.T.O unit with a twin boom system) that we called the "School Marm". So named because on the side door of the equipment locker was the mathematical calculation required for that tow truck to right a capsized battleship. A single, dual line wrecker that weighed in at about 14,000 pounds and delivered maybe 250 horsepower carried the mechanical power to drag a hypothetical battleship, that would weigh in at more than 40,000 tons, back to an upright position, made possible by the mechanical advantage of the mundane pulley. Well, that's my story. And i am sticking to it. Aloha.
Great stuff! As a young civil engineer, working for a bridge construction company, one of my regular tasks was designing critical lift plans. Basically, beam erection plans. They included selecting the right crane(s), and the required “rigging” (i.e. cable size, number of parts in the block and tackle, lifting clamps, etc. Your video brings back lots of great memories.
alright, i’ll be that guy. “hehe, he said erection” “i’ll show your wife my erection plans” “i find viagra works well for planning erections” “my erections always require cranes 😉 “
LOL I am from Cullman, Alabama. I feel you about most always coming across people who just have “know how.” I finished assembling a cheap small 2500lb winch today (welded it to an old truck receiver).. and how I have an old disc up in the woods I gotta drag out. Only have 1 snatch block… until tomorrow haha
"Jeff is the kind of guy I wanna be when I grow up" Nice to hear sentences like this from a grown man with kids and a hugely successful RUclips channel.
I am so happy I was recommended this by RUclips. This guy was fun, I loved the interaction with his kids, and all the visuals and everything about the way he teaches! The snatch block was awesome and now I’m thinking how I can use something like this at my construction job!

@@arielerosa3204 , oh well, later "Astrobrant2" posted a similar comment, and got several thumbs-up, so at least a few people are familiar with that old slang term.
I have lost count of how many times I have watched this video over the past 3 years. I love it. I went to school for engineering so we studies this in our statics class. In an odd way, this is so much fun. In an interesting follow up to this video, how does it work if the load you are lifting is you? Say you are sitting on a board tied to a rope that goes up to a pull and the slack rope comes right back down to you. To lift yourself up, how much force to you need to apply? You are both pulling the rope down and pulling yourself up at the same time.
@@willsheehan2975 No a pulley is not a lever. a lever is a rig bar resting on a pivot point, called a fulcrum, used to lift heavy loads. A pulley is a grooved wheel which a cord passes through to change the direction of the force needed to lift heavy loads. Just because they are both used to lift heavy loads does not automatically make them the same thing, that is a false equivalency. Thats like saying a swimming pool and a lake are the same thing. They both hold water, they both can have living organisms live inside it, they both allow for swimming... So a swimming pool and a lake must be the same thing.

Your enthusiasm for science and engineering is contagious! We've got snatch blocks on our wish lists now! We have also loved kiwi crates, my oldest spends hours building and playing with the awesome things they send her. Thank you for your video.
I love my snatch blocks. I have 4 of them in my Jeep. You just explained the magic of why mechanical advantage works. I always wondered how anyone discovered this and why does it even work. It's not magic, it's the constant tension! Awesome.
Happens to me too, spent my childhood in NC and AL then moved out west. I don't have an accent anymore unless I'm with a coworker who spent his life in Louisiana, then my accent creeps back out lol
I live in Georgia and when I'm speaking to another hick I can lay the accent on pretty thick but if I'm speaking to someone professionally I'll clean it up and try to speak "properly" I just like being plain spoken though.
My first thoughts were, "well yeah, everybody knows this", but then I realized that most people did not grow up playing in barns and driving Jeeps. This was my introduction to "Smarter Every Day". Great video and Destin, you are a great teacher. My Grandchildren are going to be seeing a great deal of you. Thanks.
Anyone who doesn't understand basic kinematic doesn't *really* understand. Kinematics is very intuitive, so it's easy to think you have a grasp on it. Also, just thinking about a pulley or gear as infinitely many levers and focusing on one will help (your basically just rediscovering conservation of angular momentum) However, there is always more to learn, even with something as simple as this. How does it scale, when do QM effects become non negligible. How much tension do you impart in each part of the system. TL;DR Learning how to use something and knowing calculations is fine for applied purposes. But rabbit holes are everywhere and can be fun to pull into.
"well yeah, everybody knows this", but then I realized that most people did not grow up playing in barns, driving Jeeps and calling their sister "mom".
I wasted time watching six other videos in order to try to understand block and tackle. I suspected it was a simple concept however nobody was able to explain it as well as you did. Thank you for a very well made video. Regards Your Latest Subscriber.
It works that way in many places. Southern Michigan has a general midwest accent. Then when you go back up to the upper peninsula, your accent gains about 5 power levels and graduates to Yooper.
Laminar flow isn't really a "thing". Well... yes, it's a thing, but it's not like a THING you can hold. Speaking of things you can hold, you can 3D print the pulleys we used in this video by getting the files here: www.thingiverse.com/thing:4022579
@@smartereveryday Thanks Destin, you're right. And seeing your closing montage, SNATCH BLOCK are clearly both awesome getting to your brain. I mean, with a name like that, how wouldn't they. Awesome to share those files. Not extremely complicated to make but cuts the learning curve if you don't have to design them from scratch. BTW my kids discovered Kiwico thanks to you. They had so much fun with the spinning painting disc. Learning by doing. Keep it up. I love your work (and accent). Cheers from a Canadian in Switzerland.
I like that when you're talking to Jeff, your accent kicks in. You sound like a regular guy in the video until you start talking to another southerner, then you're twangin left and right all of a sudden. Same thing happened to me all the time when I was going to school in Texas. Grew up in the Pacific Northwest, didn't have any accent at all, but when I met a real Texan's Texan, I'd subconsciously put on an accent so they'd treat me like one of their own. I remember once I was on someone's property (unbeknownst to me) when the guy comes riding up on his horse with a rifle in his hands, said "what are you boys doin on my land?" to us. I responded in the most Texas accent ever, responded "Sorry sir we didn't realize we were on private property. We're from UT, out here looking into a report of some sorta parasite that's been livin' in the streams and killin' cattle." The guy clearly figured me for a good old boy, sounded surprised about the parasite, told us we were fine to be on his property "so long as you keep me informed about this here parasite". There was no parasite, we were out there looking for lizards, but the quick thinking and the thickly laid on accent really did the trick.
lol was definitely thinking the same thing about his accent. I'm from Kentucky and the drawls definitely comes back out whenever I'm back in the state. I call switching like that "the drop."
I am rail rated on an old rail system and this video helped me understand a little more what's actually going on when we use block and falls, it's a whole graded pully system! Thanks so much for this one.
I noticed that too. I switch on/off my southern accent almost unconsciously. I spent time in Germany and never studied formally, so my German is a mess of proper German and Pfaelzish. Language is amazing.
@Trip Gil Love it Trip! That's your brain naturally making you more approachable and communicative with the people around you. The fact you do it subconsciously is just proof of your desire to be as friendly and accommodating as possible with those around you. It's a mini superpower!
WHen I was working as a professional mariner, we used the pulley concept every single day, multiple times a day. I used to tell new hires to think of blocks and tackles like using a lever; adding more pulleys was like adding length to the lever. Most seemed to get the concept pretty quickly. As long as you're willing to trade effort for distance, there isn't much you can't move. One thing that needs to be stressed is that the anchor point needs to be able to take the entire load: Not just the weight of the object, but the weight carried by each part of the tackle. Four ropes and a hundred-pound weight means a five-hundred pound strain.
Four ropes and a hundred pound weight means each rope carries 25 lbs, and the anchor point needs to support that and the weight of the blocks/rope, no more than that.
Dude, that is not true. You can't create force on the anchor point out of nowhere. If there is a 100 pound weight, there is 100 pounds (+ropes and pulleys) weight on the anchor
You mentioned that when using eg. a 4:1 pulley, you have to pull the rope over 4 times as much distance than the distance you want to lift something. It would be good to follow this with the law of conservation of energy, as in this case E=Force*Distance, so if you travel a 4 times larger distance, you apply 1/4 of the force. Just kinda ties things up nicely.
In deed the law of energy conservation is universal and explains a lot of things you encounter in daily life. From pulleys to things like computer-CPU cooling (if I put 105W into my CPU... it does not move, does not emmit light or sound (hopefully) ... so it must get hot for 105W)
That can happen subconsciously. I've noticed that I tend to reflect the accent of people I'm around if I'm around them for prolonged periods of time - even if I'm still living in the same place as I was before I started reflecting the accent.
My dad does the same. I dont have an accent. and he doesn't when he talks to me other people generally. until he talks to his family he reverts to a pretty hefty accent.
This video is perfect. Me and my kids we use winches snatch blocks all the time and they never really understood what we were doing but after watching this video, they understand . 👍
I’m trying to design a system to get my wife’s manual wheel chair into her van without effort. You may have just genuinely helped in improving her quality of life. Thank you. 🙏🤝🤞
Since you will be limited on space for a elaborate compound pulley system such as the one Destin demonstrated. I recommend looking into an inline compound pulley system. Just remember though, the more pulleys used, the more rope needed to achieve the end result. Good luck
What really clicked for me was when I realized where the trade-off in the effort was. It's not magic. As you double the force lift you must also double the distance the rope travels. Need to lift a 100lb weight 10 Feet? With one pulley you can make it feel like a 50lb weight, but it needs to be pulled for 20ft. Two pulleys make it feel like 25lbs but 40ft of "distance". all the way down to making the load feeling like it only weighs 1lb but you must make that 1lb weight travel 100x the distance. This idea preserves the energy in the system. You're still expending the same amount of energy, but in a less intense way.
What I don't get is how this effects the tension on the wire. If you need say 10 tons of force to drag a tractor out of a mudhole. Do you always need a 10 ton rated wire or will the requirements be lower with more pulleys attached?

Hi Justin. Love your channel!. Little story bout leverage and simulated pulleys through knotted rope. In 1988 I was working in a band and towed the box trailer round to our gigs containing our 1500 lbs of PA system. Long story short, the drummer owned the trailer and on one break we stood outside the venue at the cars where I said to Louie - you know what?, if I compounded the Truckies Hitch Knot on this rope to 2 and 3 knots in the same span, I could buckle your trailer. Louie said go for it. I tied the hitches together from one side of the trailer to the other side and pulled. Louie laughed at my attempt when a big CRUNK sound emanated from the sides. The trailer had crimped vertically along the sides approx centre of the way down its length. I apologised and offered to get him a new one but we bent it out and compensation went no further. The reason I mentioned this is because I was fascinated that one rope can be levered so strongly. I tried 4 and 5 hitches in the one span but the nylon or hemp ropes would snap with just the smallest of force. I saw your vid a ways back and since have been wondering what it reminded me of. There you go. Take care M8.
Because the sponsor is the kiwico thing that's linked. Saying snatch block should be called out as a sponsor would be like saying "rope" should be called out as a sponsor. It's a tool, not a brand.
My favorite part was when he said, "you dawg, I hear that you like pulleys. I got pulleys on pulleys on pulleys". I can't remember what that reference is from though.
Also worth mentioning he corrected his children without being patronising at all; getting the meaning and implementing the correction in the next sentence. Super respectful and a great way of teaching

You also have to remember when setting one of these up that the max you can lift/ pull is the weight limit of the cable or pully
Hey man, all your videos are fascinating! Thanks!
I carry rope and carabiners while hunting to set up pulley systems to get large game up steep inclines. The input end also helps me climb up at the same time. Carabiners have much more friction, so they hold the load in place better.

Shouldn't matter much, As you get more blocks in the load your line load reduces. If you have a 4:1 setup then your total load is divided by 4 and that's how much is on each line.
So if you want to lift 1000 pounds a straight pull is of course 1000, a single traveling block causing a 2:1 pulley is 500 on each line as well as a 2:1 mechanical advantage so it both cuts the line load in half and doubles the pulling force, a 3:1 does the same its 3 times the pulling force and line load is cut into 3 so you are at 333 pounds per line. If you want to get real complicated you can factor in the angle at which each line is at and that chances the numbers as the farther from 90 degrees or parallel lines the less mechanical advantage and the less line reduction you have.
@@towtruckaj but you still have the line lifting a 1000lb object at the end of the day
@@ionbusman2086 not really, with my 4:1 for example you are effectively turning 1 line into 4, so it’s really one long line that runs through a bunch of blocks but it acts as if there were 4 because both your mechanical advantage and line load are effected, for each moving block in a perfect world you get double the pulling force and line load is cut in half, so for a 4:1 moving 1000 pounds you would need to pull with 250 pounds of force and each line would have 250 pounds of force on it, so to move 1000 pounds a 250 pound rated rope would work. It’s fairly simple until you start getting into the angles of the blocks and compounded pulley setups.
So yes in short the object weight doesn’t change you are still lifting 1000 pounds, but with pulleys you can move that weight with a lot weaker equipment and a lot less force.
@@towtruckaj But where the line ties to the 1000lb object, that's the weak point
@@ionbusman2086 what you are describing isn’t a proper mechanical advantage setup, to achieve mechanical advantage the blocks have to be on be load, if you have just one line actually attached to the load no matter how many blocks you have unless it’s a compound setup you don’t have mechanical advantage, for my 4:1 example you would have 2 snatch blocks on the actual load and 4 lines 2 for each block. What you could do if you could only attach one line to the load is have one heavy piece of rigging rating for the full forces then you could compound it and apply mechanical advantage to that one line, so like a 1000 pound cable sling with 250 lb rated rope in a 4:1 connected to that cable.

From my personal experience that happens more or less per instinct and you have to 'snatch out of it' as an active decision.. 🤓🧐

"I should get back to mah truck" - 16:27
Destin, that was maybe my favorite sponsor ad I’ve ever seen. I wish more companies were open to interviews for their sponsorships.
its kinda like gear ratios, they multiply the torque at the cost of speed.
Not kinda like gear ratios. Exactly like gear ratios. The only difference is the directions of the forces.
And technically, since you most often think of gear ratio in terms of vehicular motion, even the directions are not that different. Input is the vertical movement of the piston head. Output is the force applied to the road.
So a pulley can create a ratio and change the direction of a force. While a gear can create a ratio and reverse the rotational direction of a force.
I noticed that too, I was wondering why it was so slow, but when he was moving the truck with a winch, It clicked since it took so long.
@@codeman99-dev it's also exactly like a lever and fulcrum lol. The ratio between thee distance from the end to the fulcrum between both sides is the ratio of force increase. You sacrifice distance for force and since distance is proportional to speed, one side of the lever will move faster than the other.
Instead of rpm you calculate the speed it takes for the end of the lever to go from top to bottom, since they both go top to bottom at same time but one goes a larger distance, there is a difference in speed. Plus change in direction, one side goes up, other side goes down. One gear spinsclockwise, other gear spins counter clockwise.
When you think about it, a gear is just a lever spinning around its fulcrum, and pulleys are just gears connected with ropes.
All types of mechanical advantages are the same concept really.
Or Pascal's Principle.
I know you're right but I don't understand why. All the wheels on the pulleys are the same size.
Hey Destin. I just used the "snatch block" technique with a come-along to get my tractor un-stuck from a pile of manure. THANK YOU for saving me from having to dig it out the poo! You really saved me.

I am a Mechanical Engineer who once did a similar demo on the power of pulleys in my kids' Science class, but yours was way better! Love your enthusiasm for the topic!
first, thank you. your willingness to share the power of knowledge is much appreciated. So, years ago, we had a tow truck (an old P.T.O unit with a twin boom system) that we called the "School Marm". So named because on the side door of the equipment locker was the mathematical calculation required for that tow truck to right a capsized battleship. A single, dual line wrecker that weighed in at about 14,000 pounds and delivered maybe 250 horsepower carried the mechanical power to drag a hypothetical battleship, that would weigh in at more than 40,000 tons, back to an upright position, made possible by the mechanical advantage of the mundane pulley.
Well, that's my story. And i am sticking to it. Aloha.

I have lost count of how many times I have watched this video over the past 3 years. I love it. I went to school for engineering so we studies this in our statics class. In an odd way, this is so much fun. In an interesting follow up to this video, how does it work if the load you are lifting is you? Say you are sitting on a board tied to a rope that goes up to a pull and the slack rope comes right back down to you. To lift yourself up, how much force to you need to apply? You are both pulling the rope down and pulling yourself up at the same time.

@@wanderinwolf3804 a pulley is a lever
@@willsheehan2975 No a pulley is not a lever. a lever is a rig bar resting on a pivot point, called a fulcrum, used to lift heavy loads. A pulley is a grooved wheel which a cord passes through to change the direction of the force needed to lift heavy loads. Just because they are both used to lift heavy loads does not automatically make them the same thing, that is a false equivalency. Thats like saying a swimming pool and a lake are the same thing. They both hold water, they both can have living organisms live inside it, they both allow for swimming... So a swimming pool and a lake must be the same thing.

Idk. I haven't used them before but they just seem intuitive. I have no problem understanding how they work
Anyone who doesn't understand basic kinematic doesn't *really* understand. Kinematics is very intuitive, so it's easy to think you have a grasp on it.
Also, just thinking about a pulley or gear as infinitely many levers and focusing on one will help (your basically just rediscovering conservation of angular momentum)
However, there is always more to learn, even with something as simple as this. How does it scale, when do QM effects become non negligible. How much tension do you impart in each part of the system.
TL;DR
Learning how to use something and knowing calculations is fine for applied purposes. But rabbit holes are everywhere and can be fun to pull into.

I like that when you're talking to Jeff, your accent kicks in. You sound like a regular guy in the video until you start talking to another southerner, then you're twangin left and right all of a sudden. Same thing happened to me all the time when I was going to school in Texas. Grew up in the Pacific Northwest, didn't have any accent at all, but when I met a real Texan's Texan, I'd subconsciously put on an accent so they'd treat me like one of their own.
I remember once I was on someone's property (unbeknownst to me) when the guy comes riding up on his horse with a rifle in his hands, said "what are you boys doin on my land?" to us. I responded in the most Texas accent ever, responded "Sorry sir we didn't realize we were on private property. We're from UT, out here looking into a report of some sorta parasite that's been livin' in the streams and killin' cattle." The guy clearly figured me for a good old boy, sounded surprised about the parasite, told us we were fine to be on his property "so long as you keep me informed about this here parasite". There was no parasite, we were out there looking for lizards, but the quick thinking and the thickly laid on accent really did the trick.

@@jojoAW101 Who hasn't had that experience?
Oh yeah, this is gonna be a good one. Love me some pulleys
Bill Pulley,hehe.
WHen I was working as a professional mariner, we used the pulley concept every single day, multiple times a day. I used to tell new hires to think of blocks and tackles like using a lever; adding more pulleys was like adding length to the lever. Most seemed to get the concept pretty quickly.
As long as you're willing to trade effort for distance, there isn't much you can't move.
One thing that needs to be stressed is that the anchor point needs to be able to take the entire load: Not just the weight of the object, but the weight carried by each part of the tackle. Four ropes and a hundred-pound weight means a five-hundred pound strain.
Four ropes and a hundred pound weight means each rope carries 25 lbs, and the anchor point needs to support that and the weight of the blocks/rope, no more than that.
Dude, that is not true. You can't create force on the anchor point out of nowhere. If there is a 100 pound weight, there is 100 pounds (+ropes and pulleys) weight on the anchor

"Yo dawg, I hear you like pulleys."
Never knew I needed to hear that today.
Destin is an OG memer
"I attached a pulley to a pulley so you can pull while you pull"... well, it does make sense.
You mentioned that when using eg. a 4:1 pulley, you have to pull the rope over 4 times as much distance than the distance you want to lift something. It would be good to follow this with the law of conservation of energy, as in this case E=Force*Distance, so if you travel a 4 times larger distance, you apply 1/4 of the force. Just kinda ties things up nicely.
Wouldn't it be 1/4 force per distance, not overall?
that's how ive always thought about it
In deed the law of energy conservation is universal and explains a lot of things you encounter in daily life. From pulleys to things like computer-CPU cooling (if I put 105W into my CPU... it does not move, does not emmit light or sound (hopefully) ... so it must get hot for 105W)
@Bobby T I was tired and misread the comment.

Being from Tennessee but living in San Diego I do the same thing when I’m back home and I INSTANTLY noticed that.
his alabama accent went from 0 to 100 FAST

That can happen subconsciously. I've noticed that I tend to reflect the accent of people I'm around if I'm around them for prolonged periods of time - even if I'm still living in the same place as I was before I started reflecting the accent.
My dad does the same. I dont have an accent. and he doesn't when he talks to me other people generally. until he talks to his family he reverts to a pretty hefty accent.

Hope it works out man.
Since you will be limited on space for a elaborate compound pulley system such as the one Destin demonstrated. I recommend looking into an inline compound pulley system.
Just remember though, the more pulleys used, the more rope needed to achieve the end result.
Good luck
I figured out the mystery of all mysterys THE PYRAMIDS BUILT WITH SNATCH BLOCKS.
Dylan Cla and aliens.
4philipp aliens sound extremely feasible
Stonehenge?
*SNATCH BLOCK*
Tied to alien ships...
I was thinking that. Snatchblocks were probably dropped by spacecraft and always have been alien tech.
What really clicked for me was when I realized where the trade-off in the effort was. It's not magic. As you double the force lift you must also double the distance the rope travels. Need to lift a 100lb weight 10 Feet? With one pulley you can make it feel like a 50lb weight, but it needs to be pulled for 20ft. Two pulleys make it feel like 25lbs but 40ft of "distance". all the way down to making the load feeling like it only weighs 1lb but you must make that 1lb weight travel 100x the distance. This idea preserves the energy in the system. You're still expending the same amount of energy, but in a less intense way.
Excellent understanding
Not quite the same as you loose a little energy because of friction.
Snatch Block!
simple high school physics
So that means in each scenario, the work done is equal. As work equals force x distance.
What I don't get is how this effects the tension on the wire. If you need say 10 tons of force to drag a tractor out of a mudhole. Do you always need a 10 ton rated wire or will the requirements be lower with more pulleys attached?

now hear me out here... even though I know its impossible, but a laminar flow, but around a pulley...
What an in the know comment! That was in the Veritasium combo show wasn't it?
The Real Noom ::: yeah, Real...look closely at wooden pulleys in 2nd HandStores/Antiques, they may be Lignum Vitae.....
@@yendorelrae5476 indeed
Hey I was working on a problem at my job and didn´t know how to use pulleys. Now I know, thanks to your video and I solved the problem. Thank you.
Destin: (pulleys) are my favorite things in the world
Laminar Flow: *surprised Pikachu face*
LOL That thought crossed my mind too
*applauding*
Well you can say laminar flow is a "phenomenon" and pulley is a "thing"..
12:37
Destin : " "I wanna tell you something else that's amazing, and that is the sponsor for this video, which is.."
Me : "SNATCH BLOCK!!"
Destin : "Kiwi Co"
Me : "Um, okay.."
😂😂😂
Right?
I was also waiting for that. I was so dissappointed when he said Kiwi Co, coz I was about to say this whole sponsored snatch block ad is too much!
I was already to buy too! I was like "Yeah I can use a Snatch Block!
Who's kiwi co?"
Kiddo: "it's a lot more easy"
Destin: "a lot easier"
Classic parent
An Intellectual: A lot more the easiest
CircleNoob101 I almost had a seizure trying to read that the first time.
@@cavemann_ I need a snatchblock to understand that statement easier 😅
Corrects the kids, yet later in the episode at 9:58:
Destin: "...an 8 to 1 mechanical advantage, but with less pulleys!"
Stannis: "...fewer..."
:P
That's me to everyone I know xD
With the bald tire shown at 9:17 it was no surprise the Jeep got stuck.
I felt like I was watching Sesame Street for adults... "The word of the day is: Snatch Block" "Lets count the ropes! ONE... Ah! Ah! Ah!. twoooo... Ah! Ah! Ah!"
It was wonderful.
he can totally rename the channel to that
His video on Laminar Flow was just like that as well lol.
"Hey mane, you got a purdy snatch block."
How I imagine people who are just a little too into pulleys meet and become friends.
A block of snatches... 😅
i worked on oil rigs for the last 3 years and this is literally how we make the blocks move. the 3d printed pieces at the top and the bottom there look almost exactly like the skeleton of the crown and the blocks of a rig.
we demand photos!!
Hi Justin. Love your channel!.
Little story bout leverage and simulated pulleys through knotted rope.
In 1988 I was working in a band and towed the box trailer round to our gigs containing our 1500 lbs of PA system. Long story short, the drummer owned the trailer and on one break we stood outside the venue at the cars where I said to Louie - you know what?, if I compounded the Truckies Hitch Knot on this rope to 2 and 3 knots in the same span, I could buckle your trailer. Louie said go for it. I tied the hitches together from one side of the trailer to the other side and pulled. Louie laughed at my attempt when a big CRUNK sound emanated from the sides. The trailer had crimped vertically along the sides approx centre of the way down its length. I apologised and offered to get him a new one but we bent it out and compensation went no further.
The reason I mentioned this is because I was fascinated that one rope can be levered so strongly. I tried 4 and 5 hitches in the one span but the nylon or hemp ropes would snap with just the smallest of force. I saw your vid a ways back and since have been wondering what it reminded me of. There you go. Take care M8.

* SAD LAMINAR FLOW NOISES *
😆😆 I feel Laminar Flow's pain
You beat me to it ;-;
The moment he didn’t say “our sponsor, SNATCH BLOCK” I was incredibly disappointed
Yeah at least be honest and upfront about that type of stuff.
@@WyldeTripKY snatch block is not a brand. He's not advertising.
@@MattiaBiggMattGentile do u has stupid?
Because the sponsor is the kiwico thing that's linked. Saying snatch block should be called out as a sponsor would be like saying "rope" should be called out as a sponsor. It's a tool, not a brand.
@@d1663m and it was a joke not a serious statement
This felt like some weird SnatchBlock™ infomercial. I'd buy a couple.
SNATCH BLOCK! It's for kids.
$19.95 + S/H
BUT WAIT!!!! THERE'S MORE!!!!
When he said "let me talk about the sponsor for the video" I fully expected him to say "SNATCH BLOCK!!!"
I keep a few and some limb rope in my car
I couldn't stop smiling during this video. Your illustrations are just fantastic.
"I'm really good with pulleys and stuff"
"Prove it"
"Give me a warship and I will"
"Yo dawg, here's your warship"
I wish 2019 were this simple.
My favorite part was when he said, "you dawg, I hear that you like pulleys. I got pulleys on pulleys on pulleys".
I can't remember what that reference is from though.
Andres V. Pimp my ride
"To show you the power of snatch blocks I lifted this warship!"
@@traycarrot What does a SOTA warship cost? Compare that to the average budget of a scientist (hint: one is less than the other).
@@DagarCoH archimedes wasn't the average scientist
Kids: “More easy”
Dustin: “Easier”
Then 5 minutes later he’s gone full country boy on the side of a road.
Yup, he said "less pulleys" instead of _fewer pulleys_ at one point.
But we come here for science, not grammar. :)
@@FRN2013 Stannis disapproves
Also worth mentioning he corrected his children without being patronising at all; getting the meaning and implementing the correction in the next sentence. Super respectful and a great way of teaching
@@Hevlikn YT comment sections are usually such a cesspool, but Destin's attitude has led to such insightful and positive comments such as these!
Good parenting 101; don’t remonstrate, demonstrate.
One of my favorite parts of Smarter Every Day is when Destin gets around other Alabamians and code switches into that deep south accent.
I tell you hwat.
Thank you for this video. I saw so many videos about pulleys, but none actually explained them.
