Torque - What is it exactly??

[ash t]

As the title says. I Dont know what torque is.


whenever someone says a bike is "torquey" i just agree and nod my head, im too embarrased to ask what it is..but ... what is it??

Isnt torque the 'moment' of rotation.

All it equates to in laymens (in my mind, could be wrong) is how grunty it feels (grunty = how much your shoulders feel like they are going to be ripped away from your arms when you whack it open/whether it will accelerate happily uphill and how much)

Hence why the rocket generates less power then the R1 (off the top of my head) even with 2.6 times the engine, but generates shitloads more torque with fook all revs and so even though weigh a shitload and has the areodynamics of lisa riley will beat the R1 off the line.

Simply put, the amount of torque an engine produces is how big a bang it can make. The bigger the bang, the more force, the greater the acceleration. Power is how quickly the engine can make those bangs. Faster bangs means faster speed.

Torque = acceleration.
Power = speed.

That's a very very basic way of describing it.

as bike mag put it "its the amount of punch a engine can give and power is how often the engine can give that punch"

A simplified version is how hard it rips your arms out when you accelerate.

[kasandrich]

Or to put it another way, no disrespect as the RS125 is a very capable little bike, but torquey it ain't, you have to wind it up and use loads of revs to make anything happen.

Car Diesel engines tend to have the opposite characteristics, they produce masses of torque at very low revs, giving the ability to push the extreme weight of a car, and drive very high gearing.

Torquey as an engine characteristic tends to mean producing lots of torque at low revs.

I understand fully..thanks kasandrich!!!

As i had driving lessons in a deisel i realise what you meanas you could set off with no accelerator..just careful clutch control..

and the RS...Pfft...Dont i know it!! Thats why i booked my bike test 2day!

thats it, yet get the Rs engine singing and you will out accelerate a car no trouble.

[nick_surty]

LMFAO! jka. well, i didnt know properly what torque is either, so thanx guys!

[The Tot]

Easy way to think about it is that...

"Power turns heads......




.... But torque turns wheels"

(not the movie TORQUE that is - that can't even turn shit off a stick!)

You can interpret that in so many ways but it seems to stick in my mind.

Everyone has given a discription of what torque is and what it does, but nobody has actually said what it is.

Torque is the PULLING FORCE

Taking off in 5th gear has very litttle torque, where as taking off in 1st gear has got alot of torque

An analogy:
Torque=how hard a motor can punch.
Horsepower=how fast a motor can punch.

Different motors produce different amounts of power and torque depending on their tune, For example an American V8 is almost always tuned for torque hence they seem to put out less peak power than a european model.

A simple example of this is the corvette we have. Currently it has 200 hp and 320 lb/ft of torque, but there is a cam that will give it 350hp and 300lb/ft of torque.

Jonboy, you will suffer from turbo lag and the fact that your motor is tuned to produce reasonably high horsepower, at high RPM. No matter how your torque curve is tuned, if you are not producing the horse power you won't go anywhere.

No, turbo lag isn't the issue, i'm allowing for that - my point is, why does my car accelerate harder at 5k than 3k, when it is making the same torque figure at both these rpms, if power is not directly related to acceleration in the same way that torque isn't?

[lilredmachine]

Because your horsepower is related to your acceleration. All an extremely high torque rating would do is enable you to tow caravans and get good in gear acceleration times. Pretty much every engine ever produced produces more power at peak revs, otherwise there would be no reason to rev high at all

But that's my whole point - i'm defending horsepower - torque is overrated
