I wanna know how much Hp does a human make😅
Oh wait they did it😂
@@saadaziz359Watch the video then 😅
This seemed right up your alley :)
I love seeing crossovers between my favorite channels.
hell ya! send it!!!! :DDDD
Thank you Donut for working with us on this awesome project, until the next one!
You are amazing! More power and successful projects for you in the future!
THANK YOU for this awesome video, this is like it's 2010 again and Mythbusters are at their peak.
you guys are awsome for making this video what it was
your team and company seems like you could have a very successful youtube channel
Does the effective gear ratio change as the rope unwinds from the spool?
the way Big D looks at the fire and listen 🤣🤣
he's a good boi
His name is BBC
Watt was interested in pitching his machine to people who had horses work for hours on end, everyday, on critical infrastructure like a mine's water pump.
What you measured was Maximum horsepower output. Even a strong modern horse wouldn't be able to pull their full strenght for much time. What Watt did was find out the load in which the average horse could pull continuously.
And the French repeated his experiments, but they did it on the Metric system. A CV is roughly 10W less than an HP. Which is pretty much right on the money if you consider the statistical deviations between the horses tested.
Very cool. I've had a buttload (SAE) of cars in my 51 years of driving and never actually thought about it. Great explanation.
Big D is the perfect name for this project.
Buff Horse Big D on Donut, PERFECT 💪🏾🐎
Why they gotta call the BLACK horse BIG D tho?! lmfao
initial Big D
@@dellusi0n911😂😂
the official buff horse
I love how seriously the Motivo engineers took this project. They didn't even bat an eye and just went about it as professionally as they would any other project
Heck yeah we did!
There's a TON of youtube and streamer weight lifters now, Donut could get in touch with them.
I mean it is a seriously wildly interesting question that inexplicably has no answer until this video.
@@Weekenderoameryou guys were great❤
@@Low_MarineThanks dude!!
As someone that has had to do these calculations professionally, I was disappointed until the load sensor was added. re the GPS. The distance could have been done using the cable length/your paper wheel etc but hey. I am glad you added it to check the dyno calculations as those 2 metrics are far simpler to calculate HP than the dyno and all its parasitic losses.
Regarding James Watts calculations./estimate. You need to keep in mind that his calculation is the average power he observed over many hrs ( and for good reason because its all about "work done" ) So whilst Big D produced 5.7Hp in that burst, thats not what James Watt was referring too. His comparison is to his engine that is expected to produce that power ALL DAY. So I think he is probably closer than you might think.
this
Thats a good take ngl
Also, Now the internet/People would flip if you they done this but... wouldn't whipping the horse to pull harder and faster make that horsepower higher!
The fact that i thought it would have been in the 100's is hilarious. Good content!!
Joo Mori, love your stuff man.
I mean it wasn’t running at top rpm
By definition, it should have been 1 horsepower. That it read 5 means dynos everywhere are wrong by a factor of 5. People who think they have 1,000 actually only have. 200hp.
@@srcastic8764 bruh a horsepower doesn't literally mean the power of one horse
@@srcastic8764lmao bro its just a name for a word. it doesnt actually equate to the power 1 horse produces. you might as well call it a catpower it wont mean the pulling force a cat produces
Finally, Donut answering the real questions we all wanted to know
I never knew I needed that but they came with a banger
I was really hoping it would be like,50. 5.7 really bummed me out tbh
@@BrianHYXisn’t he dead?
@@BrianHYXnone of ur buisness
Right I’ve always wanted to know, the math part in a way doesn’t seem to really show the horses actual power besides torque over a certain distance.
Big D is now the official standard when comparing the buffness of horses, with the energy to match his name too 💪🏾🐎
Pause ⏸️😅
So big D energy ? I think I've heard that before
"The Legenday 5.7 Big D"... This Horse is Amazing!!!
They used Shetland Ponys when pulling mining materials out of the mines because the height of them, and incredibly strong for their size. Maybe thats what 1 horsepower stems from?
How many Big D's does your car have?
Just out of curiosity: why not produce a dyno that's directly spooled to the horse's harness? Take the car wheels out of the equation and stuff?
the dyno is a calibrated measuring instrument. Modifying it would invalidate its calibration.
Also, PR-reasons
@@horrorhotel1999 lmaoo
Because the horse is being compared to an engine. So the horse’s power has to be the thing to move the wheels on the dyno in order for it to be a like comparison. Apples to apple. If the horse just rips the dyno wheel itself it’s not the same thing
Loved the RDR2 horse bonding message 😂 6:14
2 things:
1) Someone give the editor a bonus, as well as Big D.
2) Contact World's Strongest Man about a new event rig.
Strongman comp is a killer idea
For real! Love to see how much hp Eddie Hall and Brian Shaw can put down lol
100% let’s see it
No time limit, no weight given, just horsepower output for points. And for added strategy, BYO harness.
Horse 🐎 vs Human 💪
Jerry doesn’t know it, but he just created a video that will be replayed in science classes all over the country
Not just country, all over the world.
@@denniswaishhell yeah dawg, I am in Ukraine and I am watching it planning to show my daughter!
“BIG D ON THREE”
@@denniswaish Hell Yeah man, I am in Israel and I'm going to show this to my cool nerd friends.
It's kinda crazy to think that my 5hp vacuum makes almost 4x the power he does

The production of these videos over the years has gotten insane!!! Crazy you can access this level of content for free!
Obviously, you need to start a series of testing how many horsepower random things have
should invite some strong men
"How much horsepower does a finger joint have?"
"how much horsepower does a washing machine have"
@@mynarco_yoyowashing machine motors have a horsepower ratting on them lol
YES@@eTjendra
I was actually expecting a giant horse treadmill with a dyno under it
same here was expecting that
Yeah coz horse treadmills already exist so I was expecting that too
Same you got me, I thought they were gonna do one of those original HP tests by The diagrams at the start of video the one he said was probably never done 😂
I was expecting something similar on the thumbnail where the horse runs on a conveyor belt which in turn is somewhat connected to a Dyno.
Yep
A brilliant vid. Felt like a big pivotal moment in the making. Hope you guys get to publish the paper. Literally on the edge of my seat waiting for the number reveal.
I love how the horse agreed for a bigger feed content for the next 3 months. Smart horse. Thanks for the brilliant content
Sometimes I forget that Jerry is a legit engineer and is good at explaining these things
same because he def acts the dumbest most of the times
He’s the type of mechanical engineer I aspire to be 😂
@@breadloafbradthe reality is we sit in an office and do nth fun at all 😂
And there was me, hoping you were going to build a horse sized treadmill 😂 That would have let you measure sustained horsepower rather than very short burst.
Yes, and an actual working horse (Not this prancing Hollywood substitute) will also give a drasticly different result. For fun, search: "draft horse" or "horse pulling car being stuck"
exactly what I was wondering, why not use a treadmill type device?!
The step power of the horse would probably damage the machine in a way that would cause an inconsistency, not to mention the material issue for proper traction for the hooves, and safety for the hooves as well.@@hmezzy1771
Us moment 😅
@@hmezzy1771I mean the horse would for sure be quite confused and it'd be difficult to get the same amount of traction
The content we've been looking for for 100 years🎉❤,,, great job brothers.. ,
Love From Bangladesh 🇧🇩🇧🇩🇧🇩
Love it when dumb fun and science come together, thanks guys!
Also, the "horsepower pull" would be a fun event for strongmen competitions, lets see who can produce the most HRSPRS
This is honestly feels like a mythbusters lost episode with Adam making an appearance 😭
Totally does, no question!
When Jerry said he needed some help from engineers, I thought for sure Mark Rober was going to show up. Adam Savage and Motivo are superb expectation busters
Rober eat your heart out, Motivo is here!
Adam Savage!! No f way, that was a real surprise! Thanks for the blast from the past ❤
Never seen such a beautiful and friendly horse. Cute name too. The ease at which Big D pulls the rig also demonstrates back in the old days why horses are used to pull wagons. Damn if wagons had rubber tires, gears and suspension the horses would have had an easier time. It's amazing how much stronger an average horse is compared to a puny human
Now this is peak Donut - This is what I subscribed for all those years ago
Jeremiah has been such an amazing addition and he's really shown peak form here
agreed. i almost unsubbed a couple months ago but this is a BIG redirection in production quality i am blown away. hats off to jeremiah fr
The fact he can do this, make such a dumb idea into something so big brained, and make it all work as entertainment... These guys have got it.
Bro, this is ACTUAL science. It's like watching Discovery Channel or something. I can't even begin to imagine how much work had to be put in to get this video out.
Great stuff.
Surprise surprise working with Adam Savage is prob why it gives me that vibe
And I'm sure it was an expensive video to make with the man hours, horse rental and equipment fabrication.
To Donut and Jer, this is easily my favorite episode of content yall have ever put out. I was just googling this the other day and of course it popped up today. Super stoked with the Adam Savage cameo. Jeremiah straight up making physics history and getting an academic paper out of this so dope. Keep up the amazing videos
I love this channel! You guys never let me down. IMO it is the new Price is Right. Its always awesome to watch but definitely when you dont feel well. Its a comfort channel.
When they consulted with Adam I was like “wow how did mythbusters not already do this.” And then Adam was like “wow how did I not think of this in all those years of doing the show.” I felt good
This is probably the best episode ever made by donut. Hands down.
Exactly my thoughts! This was insane and probably one of the hardest episodes ever to make!
How many hands though? 14? 15 maybe.
Hoofs down.
In the past few months at least.
-probably-
9:00 Good call on getting help: Didn't expect him. Perfect guy to tackle old questions like this. The rest of this should be good!
Great job everyone! Loved this! Nice to see Adam Savage helping you and loving your idea!
Now that you guys have this dyno-rope-thing, I bet some of the world's strongest men would like to try this out. Maybe Brian Shaw, Eddie Hall, etc.
Precisely my thought
yeah
They pull busses and planes I think I've seen them do it
Eddie Hall drives around in an actual tank, he's a big kid at heart so this kind of thing would be right up his alley
A world champion tug of war team would be cool to see too
Huge respect for Motivo folks
My big brain homies
Big D started pulling like a locomotive ❤️
Project brain - human
Project brawn - horse
So the Scottish inventor, James watt, was pretty accurate in the 1700’s when he said his steam engine made 10hp. Incredible. Great video.
This needs to be a world strongest man competition. I’d love to see Bryan Shaw haul on it
My first thought also
I thought the same thing but with Luke Stoltman 🤣🤣
They used to do it back in the day. Rumor is they’re rotating this sort of activity back in, which is why some of the bigger guys are either coming back or doing better
Yeah they could make money tough man contest
Bryan Shaw is retired, gotta take someone in peak condition.
As a junior in mechanical engineering I started feeling like all my job opportunities were going to restrict my creativity. Motivo sounds like such a great place to work. Will definitely apply to them !!!
Yeah and considering the absolutely retarded contraption they came up with to measure a horses power instead of just wrapping the pull rope around the dyno drum gives me the impression they have a perfect spot for an incompetent engineering diversity hire on their team like you lol
I want to have my own motivo someday. Felt like I was back in university soving problems daily.
About to go into a mec e major
Good luck bro!
Seeing Adam Savage brought back memories and I loved it
Bro has the TV show potential, please consider expanding your business you're amazing
1 Big D = 5.7hp also makes Watts calculation of that 10hp steam engine to replace 2 draft horses pretty accurate
yes you're pretty right my friend!
I doubt a horse can continue pulling like this for very long. 3.75 kW power to the dyno must mean about the same goes to heating the horse's muscles. 20 minutes and the horse would be drenched in sweat and panting. 1 hp might be a simplistic and faulted approximation of a horse working for hours at a time at 1 hp.
@@wombatillo Indeed, they were only allowed to do 5 pulls, and that's with pauses in between.
They did only use a light draft horse. Friesian horses aren't bred for pulling power. A true draft horse like a clydesdale is a lot stronger at pulling as that is what they are bred for
@@wombatillo Is it "about the same" or is it about 80%? It'd still be a lot, but this is an interesting technicality.
So the spec sheet on a Challenger with 394 HP should now read: Horsepower: 394 (69 BigDHP). What an incredible undertaking! The things that can be achieved when you get the right people (and horse) working together. Great job everyone! The campfire scene was so good. High Five for whoever's idea that was.

So that means my car makes 22.28 HP
That sounds more impressive Dodge your move 🤷♂️
This was amazing. How much people can try and get done with a group is so insane. Congratulations with the outcome.
I wish there was a way to tell Big D he will forever be in the history books. What a legend.
He already knows he got it going on.😃
Bet ya a Shire Horse would be closer to 7.5 hp !!

Weirdly, this hits a spot that no viewing really has. I really need more like this 😅
That horse looked very relaxed. Didn't seem to exert all the power it had, but this definitely gives a good idea of what a real HP is :D
Not even a draft horse
maybe someone mistaken horsepower for humanpower :DD
@@TheTheMinions It seems like it
The horsepower was never intended to measure peak output, that's a modern car thing. It was for measuring the expected amount of work you could get out of a horse vs. some motor or other, and after we stopped using horses it stopped mattering all that much how accurate it is. So, a relatively relaxed horse descended from draft horses is exactly the measure we want if we want to know how much Watt was fudging his numbers to make his steam engine look good.
right so a car with 200 hp is really 200 manpower and 1000 horse power ! @@TheTheMinions
Shoutout to Motivo for thinking of all the points of failure and brining a back up. Those guys were very well prepared.
This is 1000% something I have always thought about, thank you for making it happen.
For anyone curious horsepower was first tested by how much work (a 1 ton block moving it up and down) a horse can preform in a hour that’s how horsepower was created
Can we take a moment to appreciate how well groomed the horses were? Sending love to the ranch for taking great care of their family. ❤

@@SubjektDeltaBeing pretty has nothing to do with it. Grooming a horse is part of owning a horse, and it keeps the horse healthy, happy, and comfortable
The company is "horses for productions" so those horses are all movie stars.
Its crazy how strong little electrical motors are when you see how much effort 1 horse power really is.
All that muscle mass being converted to a heavy electrical motor. It really is crazy.
Yeah some commercial laundry at my job had an motor pulled out. It was rated at 5hp. It was really dense for it's size too.
I think it’s more about the efficiency tbh, the power loss you get when pulling something in a vertical line without every movement you make being used solely to create power is very inefficient. I think it speaks more to the incredible engineers who have gone from GIGANTIC steam engines that make meager power numbers all the way down to tiny little electric motors that generate horsepower sometimes in the triple digits is far more impressive. The way they can design something to be so small yet so effective at generating power is truly incredible
Page up page up!

@@BrunoLate98
Imagine taking 30 minutes and a whole company's project just to say "15".
It's roughly 14.9hp, depending on the breed and it's RBF (relative buff factor).
I'll be short: one of the greatest videos i ever seen. I was too wondering many times, how do we actually measure this. Who gave us the standard for this. And thank you all at Donut, Motivo, Big D, Savage and all that helped. Congrats
You're welcome 😂
If only they used to plow horse you know an actual horse that pulls things
I always knew James Watt came up with the horsepower rating. I never knew how he did it though. What people have to realize is it is an average over time. Sure the horse pulled 5.7 HP on its pulls but it has to sustain that kind of effort indefinitely. An engine can and will run all day long. It wasn't brewing where horses were being used either but mining. Mines had to have large stables for their operations. It was an enormous expense to maintain. The financial incentive to get rid of all of that was huge. Everything had to be pulled out of mines. Which included a lot of water.
Only if Big D knew how much he means to the world at this moment and will remain a huge part and hold much significance to the automotive industry. He will be the one ppl will think about when talking about horse power.
Not really. He's an outlier, not average at all. This will be the beginning of a world of bad data.
He's a draft horse. They are the kind of horses that powered farming machinery in history. What do you mean an outlier?@@BariumCobaltNitrog3n

@@mycosys19:30
@@mycosyswe need tension to get an accurate answer. Where are you going to mount the horse power calculator? It is possible but it will create the process more complicated.
I think if Big D was running it would be a lot more. He was doing a simple trot and making that number. Still, all of this is super impressive. Very happy that Donut is diving into the science of real HRSPRS. I think it shows that these guys are growing and pushing envelopes.
So Watt was right. If a draft horse can pull 5 HP for short bursts, it makes sense that an 8-hour working draft horse would pull 1 HP constant for that long time, so that the horse can stay healthy and work throughout its lifetime.
This felt like a mix of old Donut, New Donut, and MythBusters. Awesome

I just wanted to say I love how seriously Jeremiah took this project.
Donut and Adam Savage is the collab I didn't know I needed and loved. Absolute perfection.
It wasn't that much of a collab though, more like Donut paid a premium to have a quick video call with Adam, who said "yeah I'd hire some engineers, have fun with that, bye".
This work was already done by GPS trackers. People who competitively ride are using GPS to see how far and how fast they are going. When using hills to increase a horses stamina and performance the rise in altitude as well as the speed and time can be converted to work in Joules this can then be converted to Watts.
All he did was tell him to not do it alone LOL still cool he showed.
*I've actually always wondered this. Also, Big D is the Arnold Schwarzenegger of horses.*
Donut, Adam Savage, and slow mo guys, collaborating on one video would be perfection. It would break RUclips!
Someone should have done the equivalent of this 50 to a hundred years ago. I asked a auto mechanic about this when I was a kid in the 80's. I'm surprised that Myth Busters didn't do something like this when the show was airing. This is one of the coolest episodes of Donut. Thank you.
They did do it and it came to 1hp over a day's work, what we see here is peak HP not sustained HP.
cars are dinoed at peak horsepower as well its good for an apples to apples comparison@@Iseenoobpeoples
@@IseenoobpeoplesLMAO no they didnt😂 also thats not how this works
I completely agree. I was so excited to see this after seeing James Watt's diagram and formula in textbooks forever. I just wonder how much the reduction with the harness going through the pulleys may have contributed or not to the results.
It is great to finally get a definitive answer.❤
Because RUclips didn’t even exist 50-100 years ago. 🤓
Watt's estimates were fairly accurate: one horsepower is roughly the average rate of work a healthy draught horse can do over a full day, confirmed by data from the 1925 Iowa State Fair and by English veterinary surgeon William Youatt.
In 1993, biologists R. D. Stevenson and R. J. Wassersug published a letter toNature in which they estimated the maximum power output a horse can muster. Previous studies had shown that the maximum sustainable mechanical power per kilogram of muscle is between 100 and 200W. Using the lower bound, they calculated a theoretical peak performance of 18,000W, or around 24 horsepower. Looking at data from the 1925 Iowa State Fair, they found a much lower real-world value. Over a short period of time, they calculate, a horse can exert up to 14.9 horsepower.
That's some big-D energy
A cameo by Adam, a beautiful horse, an amazing team from Motivo, and a great job by the donut team all together in one video. Thank you for doing this. I hope this actually becomes a proper peer-reviewed paper!
Yeah would be cool to introduce this into all kinds of current things like strongmen competitions and so on
1 horse produces 5.7 horse power 😂 brilliant! I would never have questioned it.
I enjoy the shot of Jeremiah riding the horse with a full face motorcycle helmet
Okay, seriously, is there anything that guy can't do!?
You can thank the lawyers for that! Politics = helmets
Recently started watching donut and loving it, but Jerry reminds me so strongly of Adam DeVine. I can't be the only one.
Great experiment! Maybe we start calling the old calculation “human” power? 😂 By this new calculation my ride is now putting out 2,280 horse power! Thanks Donut!

22:20 a casually day for a 3 in line engine
Seems like the obvious solution was to have the horse walk in a circle turning a beam, just like the original draught horses... that was the best solution when they were actually using the power. It would allow longer duration testing, which is critical in the definition of HP, as it's not supposed to be a peak power, but the "usable" continuous power the horse can provide as an engine. Would also be pretty easy to rig up a strain gauge for the purpose of measuring the torque.
Donut ascended to a whole new level with this one. Adam Savage, AND the assistance of Motivo and their team of engineers to build us this experiment from the ground up is just awesome. Good job you guys!!
Kudos for including Adam Savage, nice surprise 🎉
overrated
@@van3158Thanks for letting us know how you see yourself but don’t beat yourself up, I‘m sure the people in your life have realistic expectations of you.
Tbh, i reckon Big D is capable of a lot more. He didn't even look like he was trying 😂
Draft horses love to pull, but they're a living creature, you can't really force them to pull any harder than they have to. The only practical way to get a horse to pull harder is with more load, that dyno set up would need the horse to go faster for more hp when a draft horse is more of a 'constant speed machine'
I reckon its more a case of 5.7hp is what he felt like doing that day.
Best video I've seen on Donut... "science is cool" said Bill Nye
The fireside chat with Big D was cinematic excellence! Way to step it up, guys!
What did he burn?
It was the old horsepower tee shirt
16:28 lol
16:28 Big D "Why the hell did you bring me out here to watch a T-shirt burn???"
When i realized that they performed this experiment with the intention of being peer reviewed and not just for views, i was like hell yeah! These guys are out to stir up mechanical history, and im here for it.
ohh yea me too, i was afraid this was just for fun project but turns out it's for science. waiting for that sweet DOI
I don't think this experiment has any potential to be used in a peer-reviewed study. The mere fact that Big D is nowhere close to the maximum size and power of a large draft horse (like the one shown at 3:10 in the video) the potential for alternate outcomes in results is too high to warrant consideration as proof of the horsepower produced by the horse as a species.
@@grandpalarry7776 Their method is a worthy contribution on its own. The method is worthy of a peer reviewed study; just because they didn't fully answer the question, it is still a significant incremental step.
As I scientist that often does peer reviews, I would have a lot of concerns. Using only 1 horse already makes any publication impossible imo. Let alone that the set-up is unnecessarily convoluted allowing for a massive amounts of errors. Furthermore, as stated at the start, horsepower was based on the power of a horse over a long period of time, not peak horse power. These ‘errors’ all make sense for this great video and this really isn’t a critique. But calling it science worthy of publication is a bit of a stretch 😅
@@ErichteiaAgreed. Check out Nebraska tractor test.

I love the engineering of the horse to car dyno conversion project, but horse pulling dynamometers exist. But as far as I know they don't give a hp readout.
Adding that would add interesting data to horse pulling competitions.
The moment I saw the title of this video, I instantly thought, "Wait a minute, wouldn't the Mythbusters have answered this question already?" So I was both excited and astounded when Adam Savage showed up and admitted they had never done such a thing.
I liked how Adam would always magically pop out in these types of things
He never base tested with a car!
We don’t have a way to verify their calculations. If we want to be scientific, yes all this works, but at least compare the linear drag Big D could make with that of a car that you have verified the horsepower with the same dyno before, to make sure the calculations are correct, yes the calculation’s results made sense, but it wouldn’t be that hard to just hook it up to a car to see if the power lost is equivalent to the calculations. Always have the base comparison tested the Same Way! otherwise good video, and inspiring :)
As a horse owner and a car guy, I love the episode, and also want to thank you for showing Norman D plenty of respect.
Norman D?
I was thinking it was Normandy, like in France from World War II.
Checked their website though, and it's Normandie.
@@ScytheNoireI think their assumption was it was a 'big D' in his name, not just the length of his cock.
I've always wondered what the answer is, and, how might it be done. Great job.
You guys just made history and corrected a wrong we were all following
I hope the Auto industry takes this into account and will now have an accurate rating on all vehicles going forward 🤘🏽🥃
THIS is what RUclips and the internet should be like : gathering people, mixing ideas and skills, building knowledge.
This was awesome, thank you for this video.
And please give Big D a hug for us. He's beautiful !
Well GAFAM is gathering people ofr its own profit - this experiment (i fast forwarded it with adblocker) could easily be done with a weight of a horse+jockey and filming how a race horse with jockey accelerates. You would get an acceleration at each part of the race (speed) and from that simply a power of the horse at his natural load of racing (different accelerations at different speeds or as car fans could say, which gear+rpms )
Instead we get WAP music videos as Top 10 recommended!
