In today's video I'll be using Legos to give you the most visual explanation and demonstration of horsepower and torque. If you have ever been confused by horsepower and torque I guarantee that after watching this video these two concepts will never confuse you again.

So let's get started, and we're starting with Torque. Now this LARGE Lego motor outputs 0.14 Nm and this smaller LEGO motor outputs 0.03 Newton meters. What's a newton meter? Well a newton meter is a MEASURE of torque. It measures HOW MUCH torque is being generated.

What is torque? The simplest explanation of torque is that it's a ROTATIONAL FORCE. It's the ROTATIONAL equivalent of LINEAR FORCE.

When you take this bolt and push it you're applying linear force to it. But when you decide to bolt it down you're applying torque to it. In both cases a certain amount of force is present but what's different is the direction of that force.

So our LEGO motors are outputting a certain amount of torque that we have expressed in Newton Meters.

1 newton meter of torque simply equals the force of 1 Newton applied at the end of an arm that is one meter long. So for example if we take this bolt and use this wrench which is one meter long and apply a force of 1 newton at it's end the resulting torque present at the bolt will be ONE NEWTON-METER. Newton meters confuse you? No problem, because torque can also easily be expressed in foot pounds.

1 foot pound of torque is equal to the force of 1 pound being applied at the end of an arm that is 1 foot long.

So in this scenario I'm using the stored energy in my muscles to generate torque at the bolt. Our Lego motors are doing the same thing, they're using the electrical energy stored in these batteries to generate torque or rotational force, and as we have seen our large Lego motor is outputting more torque than our small motor. This difference in torque can EASILY BE FELT. If we install a small shaft into our motor we can feel the difference in rotational force coming from these motors. The difference in torque output is very obvious and the large motor feels much stronger and it's very difficult to stop it.

The convenient thing here is that these Lego motors can easily be compared to internal combustion engines in petrol or diesel powered vehicles and even more so to electric motors in battery electric vehicles.

Just like our LEGO motors THE MOTORS in modern electric cars use the stored energy in their battery packs to generate torque. On the other hand internal combustion engines rely on the energy stored in fossil fuels to generate torque.

The key word in the word horsepower is POWER. What is power? Power is the rate at which work is done, in more simple terms power measures how often a certain force is applied over a given period of time. You could even call power = activity. It measures how many times you can repeat the same action over a given period of time.

This means that torque is influenced by only one factor - the amount of rotational force

But horsepower is influenced by two factors - the amount of force and how many times that force can be exerted over a given period of time.

Now we're going to attach these blocks onto the shafts of our Lego motors so that we can more easily observe how fast each of them rotates.

As you can see the small motor actually rotates faster that the large motor. In fact over the period of one minute the small motor makes 275 rotations while the large motor makes only 146 rotations. This means that although it can't generate as much torque as the large motor, the small motor applies it's torque at a greater rate over the same period of time.

This means that while torque can be both felt and observed horsepower cannot be felt in the same sense. If we put our fingers against the shaft we're feeling the torque, we're feeling the force against our fingers. When we're sitting inside a car and the car accelerates we're again feeling the force pushing us against the seat. We can only feel the amount of force, and because torque is only a force we can feel it. But horsepower isn't only a force, it's a measure of the rate of force. In the case of engines and motors it is the amount of rotational force or torque multiplied by rotations per minute or rpm.

No, power is a cyclist. The more powerful cyclist is the lower gear he can have at the same speed of a bike, thus accelerating faster. Or the higher gear to reach higher max speed. There is no example of power vs torque. You always end up comparing power.

In a way yes. Torque is twisting force. If you were to reach out and try and stop the motor torque fells you how hard that will be. Power is forcer times angular velocity ( rotating speed). How hard something turns times how fast it turns.

A sports car and truck with the same hp can move the same load at the same rate. That's the point of hp as a measurement. The difference between them is that the truck engine needs to do it all day for a lot of miles and efficiently. The sports car needs to weight less and does not have to be as good on fule or longevity. So they designed their engines differently to better fit their jobs better.

I don't agree with you in this video and I still feel like you're falling into the trap most people do. It's about half right. You can only feel horse power. You have to apply torque over time to feel it. We can't experience things in infinity small amounts of time. It's like saying you can eat a cheese burger without the cheese. It's not a cheese burger till you have both cheese (tourqe) and a burger(rpm). I use this exmple a lot. A bike that you peddle with your feet puts out as much or more tourqe than 600cc sports bikes. But they feel totally different. It's because the sport bike can have way more rpm leading to a lot more hp.

Exactly, but force can be applied to an object moving at a greater speed. The faster you pedal the looser pedals feel: you can't apply the same force anymore. The more force you apply at the same speed or the faster you go with that same force means you produce more power.

@Igor Arkin power is force times velocity, not velocity times acceleration. Power is F*D/t, force times distance divided by time. Velocity is distance over time so multiplying by force gives you power. Acceleration is distance divided by time squared so multiplying by velocity gives you D^2/t^3 which is not power, its not really anything.

Great video! I am a bit confused however, if someone could explain how torque would give you the feeling of acceleration when: Force = mass *acc, Pow = Force*Speed, so Pow = mass*speed*acc . Which means, for any given vehicle, that has a certain mass and is going at a certain speed, power is directly proportional to the instantaneous acceleration, so the feeling you get when a car is accelerating is due to the power, not the torque.

Igor Arkin

@Levi Dieter @Levi Dieter you told the same but made unnecessary long calculations. P=a*v doesn't care about wheels, rotational speed etc, V is a vehicle speed. Power is derived from torque, exactly, this is why you don't need to to do all that tq*rotational speed/wheel diameter thing each time. You can't accelerate faster than at engine's peak power, so acc=power, discard the tq

Igor Arkin

Everything is correct. As soon as we introduce power we don't need torque or force anymore (we don't care where power came from). This is why the video is not great at all.

Torque is the rotating force of the motor, so how hard it turns. If you were to reach out and try to stop it the torque output of the motor tells you how hard that would be. Power is torque times angular velocity (rotating speed). How hard the engine turns multiplied by how fast it turns.

Can monster torque engine converted to monster horsepower engine by give some ratio gear so it can rotate faster with less torque? And vice versa?

Igor Arkin

14 dager siden

@M. Dicky Yusuf Zulahkam By increasing gear ratio you get lower rpm. To get higher rpm, you decrease the ratio (shifting down). Torque generated by engine past its peak is smaller, but it drops down slower than speed increases (your equation), that's why power keeps raising and its peak is always at higher revs. But torque generated at that shorter gear is higher on wheels. This is exactly what engine power tells you: you wanna have maximum torque on wheels - shift to peak power. If you are already at peak power - stay there.

M. Dicky Yusuf Zulahkam

14 dager siden

@Igor Arkin power is torque times RPM right? By increasing gear ratio, you sure get higher RPM. But torque generated in this gear is significantly smaller thus the power is drop. Is this what are you trying to say?

Igor Arkin

14 dager siden

By adding gears you do not convert an engine. Anyways, you can get infinite torque on wheels with any given power by shortening gear ratios (and sacrificing speed). But to get more power, you must modify your engine. If an engine already runs at its peak power, it is on wheels too. Shift up or down and you get only less power. Add more engine power to convert it to higher top speed by lengthening final drive ratio or convert it to faster acceleration by shortening it. Or use gear box to get both benefits

You've confused me more. Your equation is not accurate. HP= Torque x RPM doesn't work out. My truck makes 1500 ftlbs @1500rpm. So using your equation it makes 2.25million HP. I don't think so. It would also be helpful to explain how the measurement of horsepower is so convoluted

His equation is not complete. The full formula is ft*lb torque × RPM /5252. You have to divide by 5252 because of unit conversions. 1500 ft*lb at 1500 rpm would be 428 horsepower

Cycling uphill, if your legs can exert enough energy to go up a steep angle, thus your legs have a high amount of torque to push yourself up even though you are pedalling slowly. Cycling downhill, if your legs can cycle fast enough to accelerate down a steep angle, thus your legs were able to generate a high amount of horsepower due to your speed of pedalling, even though each time you pedal requires way lesser torque than when you're cycling uphill.

Very good example! I'd make some edition/correction: *at fixed gear. Because if you have a gear box you don't need your legs to be strong anymore: just shift down gears enough and you go uphill even with weak legs (because you didn't mention speed at which you need to climb up). So if one of the cyclists climbs the hill faster (we don't even need to know if he is strong and pushes slower or has shorter gears/smaller wheels but rotates pedals like mad) he produces more power. This is where we can clearly see everything can be described through power. You go faster uphill or down hill - you produce more power, no other way is possible.

Nevan Lowe

16 dager siden

The best way I can describe the difference between power and torque is: In all cases, acceleration is proportional to torque at the wheels. With a fixed gear ratio if the vehicle speed is allowed to vary, the torque at the wheels is proportional to the engine torque and the maximum acceleration occurs at peak torque. With a fixed vehicle speed but the gear ratio is allowed to vary, the torque at the wheels is proportional to the engine power and the maximum acceleration occurs at peak power.

Igor Arkin

15 dager siden

To elaborate more the example: we have a fixed final drive ratio (kart, electro cars). If we short it down, we will accelerate faster, despite having the same ammount of tq on motor. It is described through power: we have more power at slower speed. Power=acceleration*speed. So I wanted to say that there is no such thing as power vs torque, we don't need to know tq to judge the performance, because power includes it.

It would also be interesting to talk about instant torque. Electric engines apply their torque very quickly. A petrol engine will take much longer, coz explosion engines are much less efficient, they need to burn petrol and produce explosions, moving pistons, which is more wasteful and takes longer than converting electric energy to rotate a shaft. Diesel engine can apply torque quicker than petrol engines though, coz diesel engines are more efficient : higher compression rate, more efficient fuel. All of this is why a basic Tesla will destroy a Mustang or a Porsche on a short drag race.

Hi, engineer here. Good explanation but there's a couple of misleading points. 1. You can't spin both electric motors freely and claim that the small motor rotates twice as fast, thus can have 1/4 the torque but only 1/2 the hp. At peak rpm as shown in 5:16, the torque is effectively 0. This is true because if torque is > 0, the shafts will continue to accelerate. The rough calculations were close because the ratio of rpm at peak torque between the 2 motors is about the same as the ratio of peak rpm between them. 2. 6:25 - 6:35 you mentioned that torque can be felt but not horsepower. While this is true, it may mislead people into thinking that acceleration depends on torque and not horsepower. Let's talk about 2 hypothetical engines, A and B. A has high hp low torque. B has high torque low hp. Torque at the wheels is what matters and A can be geared down to produce more torque than B at any specific speed. Put the sports car engine in the truck with a custom gearbox (or a perfect CVT) and it will accelerate the truck faster than with a truck engine. The real reason why trucks need high torque engines is for fuel efficiency and reliability. You can't redline a high hp low torque engine for 12 hours everyday.

Your statement at around 6:20 that "you feel the torque, not the horsepower" is vaguely formulated and not entirely true. Also, the car footage suggests that you feel the torque of the engine, which is NOT correct. Since the engine is not connected to the wheels directly, you can only feel the torque after being magnified by the gear box. And, more importantly, the gear ratios will inevitably depend not on the engine torque but on the engine power (hp). Therefore, you are practically feeling the horsepower. If you disagree with me, compare the feeling of accelerating a low torque, high hp (by means of high RPM) vehicle vs a high-torque, low hp vehicle.

It might have been worth mentioning that the torque generated by the truck engine is not only due to larger cylinder volume and piston diameter resulting in greater reciprocal force through combustion but equally important is the greater distance of the crank throw from the point of rotation creating a leverage effect for that force to act upon. It would have tied nicely into your example of torque measurement using the 1 metre lever bar on the bolt with the applied force.

Why does noone explaining the difference between hp and torque show that time doesn't matter for torque? You came close but a visual representation would have been easy at that point. E.g. it doesn't matter how long the bigger motor needs to move the "heavy attachment", important here is that it *can* move it (while the smaller motor *would* move it much faster but can't do it due to the lack of torque).

Igor Arkin

@Redtooth 75 anyways No movement means no power Slow movement or low load means low power Fast movement or high load means high power. Force does everything, but it has to be described through speed. You cant measure tq on wheels of two cars and do the judgement without knowing speed at which tq occurred. So tq is what needs to be factored with speed (time). Power includes them both so we don't need to know if it is 600hp @ 1800rpm (and, say, 30mph car's speed) or 600hp @ 6600 (at 180 mph): we r gonna move the same rock at the same speed with both engines

Very nice, but still missing a key point that it's the horsepower that really matters to move a vehicle. If you have enough power, you can multiply the torque by reducing the gear ratio... A truck needs power at very low speeds, so the most effective way to have and deliver all this power is with a lot of torque.
