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.
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.
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!
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.

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.
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.
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!
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.
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.
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 😉 “
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!
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.
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
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.
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".
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.
"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.
@@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.
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.
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
@@billledbetter2361 His inflexion rolls a lot more (like, more becomes 'mo-e') as soon as he talks to people on the field. While on camera he uses a less inflexed speech.
@@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 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.
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.
@@PrimetimeNut People naturally mimic those around them for different reasons. Don't hold it against them. In fact, if you can play it up genuinely, people like you.
Awesome explanation and fun, this rocks! Something I just realized phenomenal about a compound pulley you demo, is each pulley could be tethered to SEPARATE objects to divide the load. So if you had weaker trees, you could tether to separate ones and still get the job done!
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!
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.
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.
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.
Scottish here but yeah, 100% anyone with a strong regional accent has to modulate when talking to an audience from outside the region. Used to live in a flat of 3 Scots, a Dutch man, a Spaniard and a French man, all fluent English speakers. Still, no one could understand us when we spoke between ourselves, so we all had different accents for speaking as a group.
Dustin, can I just say that I thought your sponsor was amazing, the first time I ever watched the whole advert bit, what an honest and worthwhile company :) times are a changing x
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.
Haha I had a physics professor in high school that drilled into our heads mechanical advantage of a pulley and basically the inverse relationship between distance traveled and force applied between the two end points. However compound pulleys are something I never could quite grasp until this video, the demonstrations make it so easy to understand.
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.
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.
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.
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."
Destin, your section that included getting your Jeep stuck reminded me of a pair of tricks my father taught me about mechanical advantage. Neither use snatch blocks but both are useful if you have a length of chain or, in the case of being stuck a stout rope. Dad had taken a friend and I sledding (and wood hauling...), this is about 1966-7. He drove the old 4x4 out into a flat field that had 8" of powder snow and we set off to buck some birch and do some sledding. Upon our return, we discovered that under all 4 wheels of the truck there was a thick layer of solid ice. Even trying to ease the truck into motion wasn't happening, all 4 wheels were spinning as if the truck was on a hoist. Dad pulls out a length of 1" rope, tied it to the frame (separate lesson on a bowline knot) and instructed me to proceed with the other and to an anchor tree, put a wrap around it and pull it as tight as possible. He got in the truck and instructed my friend to push on the rope at the center of the line between truck & tree at right angles to the line. My buddy was able to push the rope 2-3 feet moving the truck just an inch or two. Dad applied the brakes, my buddy let up on the pressure & I took up the slack at the wrap at the tree. Rinse & repeat until we'd moved the truck a few feet where there was a little traction and we were free. This is the power of trigonometry! The force applied was my 50-60 lb. buddy on an icy surface to the rope, but the force applied (at first) to the truck was perhaps 30 lbs. / sin(~179.9999 degrees) or bunches (>100,000 lbs.)! As the angle drops from ~180, the force drops rapidly too, but a hundred foot rope keeps a high angle to this point for several feet. The other mech advantage trick was using a length of stout chain (35-40 lbs. 10') bolted to a stubborn axel in an old tractor needing removal. Using the mass and momentum of the chain to yank that axel in a couple of tries. I don't miss the cold and snow of Montana, but I do recall lessons well received... :)
aw, awesome trick. p.s. I don't think the force reached 100,000 lbs, any rope has a bit of a give in its length, so when it finally extends to its full length the angle is already less than 180
@@vsm1456 Good catch! Being an electronics guy, I recalled the reason for the 'sag' of power lines between power poles and gravity pulling down on those lines removing any possibility of hitting 180 degrees (straight and flat) ... Because... infinity. I used the 'theoretical maximum' of it being near dead straight just for the calculation, dramatic effect and to show how strong I was as a strapping 8-year-old pulling the rope tight... :) The initial force on the truck (and the tree) was likely on the order of an average of 1000-2000 lbs. for an inch or two, but the point is made... it works well.
I have gone my entire life without knowing about snatch blocks. I could have used these in my past. Thanks for a great video, well explained and great enthusiasm.

You must respect the wires under tension. If they snap, they can kill.
just like Thanos do
Ok Can’t blame u if I want to shoot me lol
Well... Mythbusters kinda showed it's not That likely the get killed by a wire.. but never go under a load.
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.
9:21 People of the internet! Please DO NOT stand that close to a cable that is under tension!
9:25 the jacket on the cable according to some old timers will stop the cable from snapping back should it break but I wouldn't wanna test the theory

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.

Great video and Destin, you are a great teacher. My Grandchildren are going to be seeing a great deal of you. Thanks.
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.

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.
40,000 tons?

@@wanderinwolf3804
If you just push the ground, you can already do that
@@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.
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.

Jeremy is extremely smart and a great teacher. You are as well. Thanks for sharing your videos with the rest of us!
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.

Dude modulates his accent heavily depending on audience. Fairly nuetral for RUclips, and thick southern for roadside truck help.
I'm the same way if. I'm talking to someone with a southern accent it brings out my accent.
Most Alabamians are quite similar. It’s a way of relating better with the older generation and the uneducated.
Scottish here but yeah, 100% anyone with a strong regional accent has to modulate when talking to an audience from outside the region. Used to live in a flat of 3 Scots, a Dutch man, a Spaniard and a French man, all fluent English speakers.

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.

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.
you passed a real life speech check
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."

Destin, your section that included getting your Jeep stuck reminded me of a pair of tricks my father taught me about mechanical advantage. Neither use snatch blocks but both are useful if you have a length of chain or, in the case of being stuck a stout rope. Dad had taken a friend and I sledding (and wood hauling...), this is about 1966-7. He drove the old 4x4 out into a flat field that had 8" of powder snow and we set off to buck some birch and do some sledding. Upon our return, we discovered that under all 4 wheels of the truck there was a thick layer of solid ice. Even trying to ease the truck into motion wasn't happening, all 4 wheels were spinning as if the truck was on a hoist. Dad pulls out a length of 1" rope, tied it to the frame (separate lesson on a bowline knot) and instructed me to proceed with the other and to an anchor tree, put a wrap around it and pull it as tight as possible. He got in the truck and instructed my friend to push on the rope at the center of the line between truck & tree at right angles to the line. My buddy was able to push the rope 2-3 feet moving the truck just an inch or two. Dad applied the brakes, my buddy let up on the pressure & I took up the slack at the wrap at the tree. Rinse & repeat until we'd moved the truck a few feet where there was a little traction and we were free. This is the power of trigonometry! The force applied was my 50-60 lb. buddy on an icy surface to the rope, but the force applied (at first) to the truck was perhaps 30 lbs. / sin(~179.9999 degrees) or bunches (>100,000 lbs.)! As the angle drops from ~180, the force drops rapidly too, but a hundred foot rope keeps a high angle to this point for several feet. The other mech advantage trick was using a length of stout chain (35-40 lbs. 10') bolted to a stubborn axel in an old tractor needing removal. Using the mass and momentum of the chain to yank that axel in a couple of tries. I don't miss the cold and snow of Montana, but I do recall lessons well received... :)
aw, awesome trick. p.s. I don't think the force reached 100,000 lbs, any rope has a bit of a give in its length, so when it finally extends to its full length the angle is already less than 180
@@vsm1456 Good catch! Being an electronics guy, I recalled the reason for the 'sag' of power lines between power poles and gravity pulling down on those lines removing any possibility of hitting 180 degrees (straight and flat) ... Because... infinity. I used the 'theoretical maximum' of it being near dead straight just for the calculation, dramatic effect and to show how strong I was as a strapping 8-year-old pulling the rope tight... :) The initial force on the truck (and the tree) was likely on the order of an average of 1000-2000 lbs. for an inch or two, but the point is made... it works well.
Thank you for this video. I saw so many videos about pulleys, but none actually explained them.
I have gone my entire life without knowing about snatch blocks. I could have used these in my past. Thanks for a great video, well explained and great enthusiasm.
"Dad, am I your favourite?"
"No, son. This snatch block is my favourite"
"Then there's laminar flow, slow-mo cameras, dominoes, Prince Rupert's drops, eclipses and of course rockets. But I'm pretty sure you're on my Top 100... I guess."
Dad why's my sister's name Rose?
Because your mother loves roses
Thanks Dad
