Now I understand how my wife feels when I explain something to her about cars...

Thanks, I almost understood.

Perfectly Understood. Now can you repeat the part where you said all the stuff about the things.

I think it’s easier for cyclists to understand this because at some point you cannot press harder any faster, but you can drop a gear press just as hard much faster and make the vehicle go faster.

This Guy : Explains everything perfectly My mind = ok we need a longer car for more power 😆

there's no school like youtube

I understood the introduction. you lost me at 99 percent of the video.

Rewatched some of your early videos after being a viewer of about two years and the progress of how you come across on camera is incredible. Practice makes perfect and you can tell that you’re far more comfortable on camera now than you once were. Long time fan, love the videos.

This is how it would be thought of in a physics lesson. It might help. Torque is a turning force. And you can use that force to turn, or revolve, something - like a screwdriver. And by applying torque, you can make that screwdriver turn a revolution. By doing so, you have completed 'work' (though a fairly small amount). Torque is measured in either Newton Metres, or Lbs Feet. In this explanation, we will just keep things simple - think of torque as brute strength. Horse Power is a method of measuring how much work is done in a given time. You need to know how much torque is applied, multiplied by how many revolutions per minute that torque is applied, to work out how much horsepower is achieved. This is the way I think of it... There are two piles of bricks, one hundred in each pile, and they need moving across a building site. A muscle man and a marathon runner challenge each other to a race. To see who can move a pile of the bricks the fastest. The chap with a lot of muscle and strength (we will think of him as having the strength to apply lots of torque) is built like Ronnie Coleman. He is big and immensely strong but heavy and quite slow as a result. He is quite capable of scooping up a whole load of bricks and carrying them. He can carry 20 bricks at once, but he SLOOOOWLY.... walks with them. He could move all the bricks in 5 trips and take 10 minutes. The seriously fit runner, who is light and fast on his feet (think of Mo Farrah) might only carry 2 bricks - 1 in each hand - and sprints across the ground. He has a low amount of muscle (or torque) but his legs can run (a form of revolution for our example) at a really fast rate. It takes the runner 50 trips to move the bricks. Also in 10 minutes Now if they both complete the task in the same time, then they have both done equal amounts of WORK (which can be measured in Horsepower or Kilowatts) and It's a draw. However, if Ronnie Coleman could manage to carry 25 bricks per trip, at the same pace, he does it in 4 trips, and in just 8 mins. He will have put out more horsepower. He carries bricks at a slow pace compared to Mo, but by applying more strength (or torque), each rpm is doing more effort. Then it's just a case of multiplying the two together. Torque X RPMs. However, Mo Farrah - still only carrying 2 bricks - refuses to be beaten!!! He hasn't got the strength (or torque) to carry more than 2 bricks, but he can pick up the pace instead. So he runs faster and his legs are a blur!!! . He finishes the task faster than Ronnie, let's say 7 mins. His body, although weaker at lifting, has now worked harder, because his low amount of torque, could be multiplied by very high revs. Think of a motorbike screaming along at 16000 rpms.... Lots and lots and lots of small, easy efforts, all added up to one huge effort to beat Ronnie. And he has now worked the hardest Mo Farrah's incredibly hard work (measured in horsepower) meant he was moving more bricks in a given amount of time. Keep this example in mind and think of your car engine. Horsepower is simply a way of measuring work done in a given time. It is not a unit of force, or a measure of how fast it can travel. The ability of an engine to provide power is achieved either by applying large amounts of torque at low revs, or applying low amounts of torque at high revs. In real life Ronnie Coleman is built like a truck and would most likely win the competition in our example. He would be more efficient as he wouldn't be wasting time picking up and putting down bricks 50 times. Plus Mo Farrah would probably have to run at some ridiculous speed like 40 mph. It's just not feasible. You couldn't expect a motorcycle to carry bricks - it's not designed for it. The truck is. An articulated lorry tractor unit or semi - truck (if you're in America), might have 600 or 700 horsepower but that is only an indication of how much work it is capable of. If comparing two vehicles to see which is faster, then look at POWER TO WEIGHT ratio. Although so many other factors affect performance: air drag, rolling resistance, a final drive ratio affects acceleration, fwd,rwd, awd, tyre traction.... etc etc etc. Its never simple. When office workers talk of how much work they have done that day - scientifically that's not really the case. It does not take a lot of horsepower or Watts to pick up a few pens, or shuffle some paper. The man who's outside, lifting and carrying all day long, has worked much harder. Something my boss could never understand when I tried telling him that office work is not real work! (sorry office workers. I mean no offence; that's physics!)

Jason, you’ve just answered the question that I’ve had for years! I knew of torque, I knew of horsepower, but couldn’t determine how they intermingled on a power curve. Mind blown today when you pulled it all together

Think of it like this: Torque is how much weight you can bench press, horsepower is how many reps you can perform with that weight in a certain time frame. EDIT: I tried to keep it simple by mentioning "time frame" because you have to have some way of measuring how fast the weight is being moved in the example I've given. Which is confusing some people on RPM's vs horsepower. Think of your RPM's as being your rep count. And your horsepower is how fast you can move the weight to that rep count. For example..if you have two bodybuilders that have the same torque but different horsepower, it's going to take the one with a higher horsepower less time to get to 10 reps than it will the bodybuilder with the lower horsepower. Even though they are both lifting the same amount of weight and doing the same amount of reps.

I'm on a 32 inch monitor and at 4K it feels like you're sitting and explaining this right in front of me in person while I'm sitting on the opposite side of the table. Love the quality and explanation!

Man, I swear, between you and ChrisFix, I get a good dosage of car related knowledge, you two guys and a few out there are really professional when it comes to stuff like this, thanks for helping us out with these amazing vids🤘

There's no denying the fact that this is the most simplest explanation one can find regarding the difference between torque and horsepower. Spectacular work Jason!

Advantage of UKposts - you need not feel embarassed for not getting it in the 1st go. Just double tap on the LHS

I couldn’t have asked for a more informative yet succinct video with visual representation too. Instantly subscribed as you turn complex theories into fun examples that are easy to understand!! Thank you ☺️

You lost me at "hello everyone and welcome"

This was the best explanation I've heard and I think I'm pretty confident in my understanding of the relationship between torque and horsepower now. Thank you so much

I think the reason so many people struggle with this (myself included) is that it is ultimately NOT simple. Much as I enjoy EE's videos, it's possible that an engineer is not the best person to explain it ;-)

Horsepower is how fast you can turn the wrench, torque is how hard you can turn the wrench.

Nothing causes more arguing and dissension than Politics, Harley Davidsons and the definition of torque.

The explanations using the peak values graphs were really good. Nice work, great perspective.

This is so much better of an explanation than every other 30 minute filler video… thank you so much

Thumbs up for the explanation and LEGO Shell Limited Edition Ferrari F40 with pull-back action :P

Thanks for watching everyone! I think one question that may come up after watching this is "Why does maximum acceleration happen at peak horsepower, rather than peak torque?" It's a fair question, because in a single gear ratio, peak acceleration (the force pressing you back in your seat) occurs at peak torque. I have a video explaining this in great detail: ukposts.info/have/v-deo/m5Jnpn-RnXmmqX0.html Edit: Also, if you're confused about the equation for Horsepower in this video not including 5,252, I did this to simplify the video. 5,252 is a scaling factor only appropriate for imperial units, it is not useful if you use kW or N-m, so it's inappropriate to use 5,252 in a general equation. I will include a video in the future explaining exactly where (through derivation) 5,252 comes from.

Great video. I have watched many and enjoy the topics and the way you explain it. Would have loved to have these back in the early 90's when I was part of our LeTourneau SAE club and teams doing design projects like the Mini Baja, Formula SAE, and the High Mileage competition.

I came back across this video; many automotive reviewers should watch it to under stand torque is not the end of all things when they are not completed off the track to start with. Great explanation!

Wow what a simple explanation.. you made this very simple . Icant compliment you more because im not so good in english Love from india

I'm very mechanically inclined and have heard the HP v Torque explained in about 10 different ways. I still don't understand it outside of "torque is how much load can be hauled" and "HP is how fast you can haul it."

Brilliantly explained. Finally I can confidently say I could understand the basic fundamentals and connect why certain cars move faster inspite of having a lower capacity engine horse power.

I've wanted a good explanation for this for years. This is amazing, thank you.

Also explain why diesel have more torque than gasoline for same engine size... Greater compression ratio > longer connecting rod > larger crank radius = larger distance = more torque 😊

I like this video a lot more than your others. Don't get me wrong I love all your videos, but it's nice to understand an entire video. Even if I understand your math based videos I can't apply that knowledge in real life, this I can apply to grasp a better understanding of how my car is working when I'm driving my standard car. That will help a lot

The best explanation I heard on HP vs Torque, been searching for video like this. I understood it perfectly. Thank You EE

Getting clearer each time I watch this. Thanks

I was following you up until it all got complicated 😂😂😂

Videos like these are why I'm subscribed. Keep it up man.

You explained it so simply .. your explanation style was superlative !!

Probably the clearest explanation I've heard thus far. Got ya the first time around, though I am mechanically inclined as well. I prefer torque, because I like the usable power at a lower RPM.

The confusion comes from the inclusion of gears in the simplified equation. Look at tractors and their high torque and low hp engines. Look at why hot-rodders turbocharge their cars. Early HP doesn't necessarily translate into quicker acceleration, but early and consistent torque does. Work performed is such a simple statement. Using your long handled wrench as an example - you get more torque with it. Make one revolution every minute. Now every 30 seconds. Now every 10 seconds. Getting tired? Now every 1 second - generating the same torque but doing more work - hence higher horsepower. Now if you add gears, you can magnify your torque and your horsepower as you see fit, carefully trying to find the right balance with your human engine. If you add a 10 foot extension to your wrench, you'll get super high torque, but very little horsepower as its a lot of work to go one revolution. If you shorten it, it will be harder to get up to speed, but you can spin it much faster. This is why we have multiple gears; so we can have usable torque and HP. Now if Hafþór Júlíus Björnsson takes over for you and does the turning, he can generate more torque than you. He may not be able to spin it much faster, but when you factor in gears, his torque will spin a gear faster, doing more work and hence more horsepower. I hope I didn't mess up too bad with that explanation. And we haven't even got to engine torque vs torque at wheels....

I wish all of my college professors were as clear and concise as this!

Thanks Bro, I am a great lover of science and tech, but I was bit confused. Now you cleared me most. I will watch once again

Thank you man for the amazing information, it’s my first time to watch you and guess what, i’m subscribing🔥🔥

A great explanation (after multiple rewinds). I’d love to see a follow up video of this in practice - building on the concepts explained with a couple of vehicles with varying hp & tourque. Dare I say... factor in electric engines too?

Think of torque as how hard your pistons are pushing with each crank, and horsepower is the combined energy of each push over a fixed period of time. The more times that torque can be applied, the higher your power output will be. The faster your engine turns over, the harder it is for the engine to apply torque, since the pistons are already in motion. It’s like trying to hit a baseball which is already moving away from you. That’s why torque tapers in the high rev range, but power continues to increase, since you have so many cranks per minute!

Your way of explaining is so easy to grasp

I always remember on our local dual carriageway on my cheap and nasty long stroke 250cc CZ motorbike sedately chugging past a Yamaha 125cc which had probably double the horsepower with the other rider lying flat on the tank trying to make way in to the head wind. A good demonstration of torque and a rare and memorable memory at not feeling at the bottom end of motorcycle ownership.

This has become my favorite UKposts channel. Keep up the great work!

I loved the joke at the end about how it cleared up the differences between hp and torque

A good explanation I understood: You can leverage torque, meaning the force applied will be greater but the lenght of the leverage arm will increase linear. So the power is always the same, as long as you move your arm in the same speed aa before. When you increase the speed you will increase the power, while the torque applied stays the same. In ICE cars its not only the speed which increases but also the torque, at least at low rpms. Thats why you get a very step power increase. Then torque will start to drop, but not as fast as speed (rpm) increases, so power will still increase. This explaination will give you the answer, why a human cannot have the same hp as a car although with a large leverage arm the torque applied by human hand could be greater: you cannot do it with 7000 revolutions per minute

Your videos really helped me understand engines, and they way they function.

when i started racing speedway i was told hp is how fast you hit the wall and torque is how far you move it lol

What a Simple, Objective and Clear explanation. Congrats and Thank You Very, Very Much.

One of the best "simple" explanations I have ever seen. If one does not get it after this, that person will never get it.

Crazy! I remember watching this a while back and not understanding it but after just taking physics mechanics in college I easily understand it now.

Loved the video! This is the best explanation of this topic I have found

More confused than I was before watching 🤣😭

I think explicitly stating (or showing how) you can compensate for less torque with gearing but you can't compensate for less hp with anything helps clarify.

Great explanation, I really like your videos! You just got yourself a new sub!

Peak Toque was my favorite Monkee. So sad when he passed away.

So many people will understand this practical/theoretical analysis much easier than some of the mathematical explanations he uses in most videos 😁 this makes is very easy to understand though. Great work 🖒

I love the way you explain it all. Thank you so much.

Probably one of the best torque vs hp explanations.

I had that confusion for a long time , I asked my brother to explain but I still had the confusion ... You have done a great job of in explaining , now I have no confusion! Thanks!

Dude you're the best. I was asked this a few weeks ago and couldntbexplain it properly. You made it so simple. Thanks so much for the great videos!

So good can’t express in words wish to learn more from you keep up the good work

Thank you! You are very good at explanations and visuals.

thank you! I've been wondering this for awhile. You explained it really well, good job mate

Yeah baby !! ... Finally, torque and horsepower explained simply. I'm linking this video to my upcoming episode of blowing up see-through engine, match made in heaven !!!, you'll see what I'm talking about Jason.... Fantastic !

Third time I’ve watched this. I come back every 2 or 3 years for a refresher to make sure I don’t forget little things. Thanks for the video!

Thank you so much! I can now actually explain what torque is and mostly understand what you were saying in the latter half of the video :)

Your explanation here is the clearest I have heard so far. Thank you for the video.

I love you man!!!!!! 46 years old man here always had that question in the back of my head but never actually asked anyone. Today out of nowhere i stumbled on your video by accident and watched it . It is so amazing the experience i mean, when you meet a true educator that have this ability and charisma to explain complicated maters to people that have no clue or any idea about the specific subject. After all when you cant explain something to a 5 year old it means you dont truly know that something! Love from Sweden keep up the good work!

Loved the video ,you answered my question that I had for years and you confirmed my theory I had for years.!!!

Explained well and understood it because it was so well explained- many thanks

i changed my mind, i prefer to buy 1 horse with chariot. The End.

Horsepower sells cars torque wins races. - Carrol Shelby

i think it might be helpful to see a graph of wheel torque over engine speed at each gear

Euro Truck Simulator 2 brought me here. I needed to understand which truck I will use. You explained both simple and straight. Thanks!

He is better teacher than all my teachers combined. Bruh.

Literally 1% of the people in the comments understand it. 89% think they understand but still dont get it, it and 10% are still like.... what

Man you save me a lot of time for my curiosity while studying elective thankyou so much

Thank you friend, I saw this video very late, but it's more informative and understandable in a simple way..i apericiated.... good work..

As a former motor head we always said torque gets you off the line power makes you finish. I been a Auto tech since 1996 and what the automotive industry has done with small displacement engines is truly amazing. The power numbers from 4 cyl engines is truly amazing.

Man, I just love how you explain things in such a simple way. One of the best channels honestly. 👍🏻

This video and someone else's is helping me understand the relationship between torque, rpms and horsepower. I think the main problem is that I've never fully understood torque. I mean it's obvious and easy to understand in some ways but it's not something you can visualize. I think I have the same problem with volts. I get current because I can visualize it flowing but volts seems to be a relationship between current and resistance so it's not a tangible thing, it's a relationship. I think if someone said torque is not a thing it's a relationship then I would of understood it many years ago. Basically it's a force so it is power but influenced by distance and leverage which makes it always a force under a gear ratio. And that gives it a relationship with the actual initial force I guess.

Thank you for this video. It was very clear and I think I better understand now. I did wonder what it was about as I have been looking at buying a new car with turbo and did not understand the torque number.

Your reviews reflects how Awesome is your Video..Thank you is not enough you deserve way more than thank you

Thank you for that easy to understand explanation!

Thanks for clearing it out

This video is really good, thanks for explaining 👍

Superbro. I am able to clarify most of my doubts via your video. Thanks a lot

so, a funny story here, I was trying to make hummus when the blender gave up on me, so being the nerd I am, I was trying to understand what exactly happened... here I am 3 hours later deep in researching power and Torque I just wanted some hummus!!

Very well put video mate. Thanks from Australia

Listened to it 3 times and understand approx 50% of what he's saying as I follow along trying to decipher my dyne graph.

u lost me half way,gonna keep rewatching it till i get it 100%,great video man,keep it up.

Great video. Especially impressed with the ability of being able to utilise medieval units of measurement.

You have explained so nicely n so simply. Thanks a lot.

Nice explanation, finally understood the difference.
