Does anyone understand torque?

Question

My physics final is tomorrow, and I only have a very vague understanding as to what torque really is. Can anyone give me a good explanation using terms like moment arm and axel?

Answer 1

This is just to give u a little help. Because I am no physicist. This is how a friend of mine who is really into cars explained the term to me.

... Torque is the force that a car has to tow another vehicle. For example a Trailer has a lot of Torque power and it uses it to pull the weight it needs to carry. A Ferrari, for example, has very little Torque because all the Horse Power it has it is used to go quickly accelerate.

That's why perhaps you don't see many cars pulling an RV or a boat. You would normally see SUVs or heavier trucks doing the all the hard (pulling, towing) work.

Hope this helps understand the concept.

Answer 2

When a force is applied a body is accelerated in the direction of force.

This is understood as far as linear motion is concerned.

But in the case of rotational motion, it is a different one.

If a rod or door is free to rotate about an axle, the door rotates if we apply a force at some point.
If we apply the force very near to the axle, we find it difficult to rotate. We exert greater force to rotate it.
If we apply the force at some point farther away from the axle then we find it easy to rotate the door. Now it is enough if we give a very small force.

Thus the rotating effect depends upon two things; one the force and another the distance from the axle.

Larger the value of the two, it is easier to rotate.

Thus for measuring the rotating effect, mere force is not enough. The product of force and the distance of the force from the axle are considered.

The term used for this product is Torque.

arm~could be associated with the performing of the act of torquing something. as when a person take a wrench and torques down a bolt and a nut together to tighten it so that it locks in a very torqued manner measuring that it has been thought out what the individual wanted as conditions for it to lossen were substantially reduced by over tightening it to a given hypothetical value achieved by the use of muscles(arm)

axles~extend to wheels usually and on car there are wheels at the end of the axles and each lug nut on a Axel is torqued on in the world today as the aluminumm wheels have to be torqued after the rims have been removed to change a tire after you have changed the tire you then have to take the time to check them again as the aluminum rim tend to lossen and the torquing is recommended as a way of have your wheels from falling off or loosing a lug nut cause the aluminum doesn't stay in place with only a one shot tightening they have to come back and be torqued after a half hour road test

Answer 4

Torque is best described as a twisting force. Like when you twist the handle of a screw driver you are putting torque (twisting force) on the screw driver which is transmitted to the screw causing the screw to turn.
Torque is measured in either toot pounds or inch pounds.
Another good example of torque that is easy to understand is what is known as the torque wrench. You set it to however many pounds of torque you want to put on the screw or nut. and when you push down hard even that you have generated that amount to torque you will hear the wrench click to let you know you are exerting the set amount of torque on the nut or screw.

Answer 5

See http://en.wikipedia.org/wiki/Torque

Torque is the twisting force that results from a force acting at right angles to some point on an object (usually a fixed pivot point). The magnitude of torque is the distance from that point to the place of application of that force times the component of force at right angle to the line from that point to the force.

Answer 6

see a door can open when u apply a force only at the opp end

this shows that there is another thing other thatn force

and that is the distance from the pivot


and torque is there product


and what a nice time to ask that question

Answer 7

torque is the ability to turn something. It is the product of the force and the perpendicular distance from the line of action of the force to the pivot. The larger the moment the easier to turn something attached to a pivot.

Answer 8

It's a measure of how much a force acting on an object causes that object to rotate. The object rotates on an axis (pivot point). The distance from the pivot point to the point where the force acts is called he moment arm.

Answer 9

question a million- 500hp with little tq. Horsepower is a style from the torque score and rpm/5252. in case you have one engine that produce max tq of 200ftlb at 4500rpm then that's produce 171 hp. in case you have yet another engine that produce max tq of 200ftlb at 14000rpm then that's produce 533 hp. So, they figured to bypass with the severe rpm then severe tq in highway racing bc race automobiles does not weigh lots and that's the place the transmission additionally come to play. Transmission is s bunch of gears. Gears are what they referred to as mechanical income. think of of a bicycle, they have gears. Your legs are the engine, you may in straightforward terms bypass so quickly in 1st kit, besides the shown fact that that's up on your legs, in the experience that your leg can bypass swifter then the bike will bypass swifter, besides the shown fact that that's extra suitable to alter the kit ratio, for that reason changing to 2d kit. blah, blah, blah...a lambo can bypass to 60mph in 1st kit, yet that's bc their engine can rev that best. besides, getting too long. in a nutshell transmission, a mechanical income device. how briskly a automobile is going continues to be determine with the help of the engine. ie an previous corvette to realize that's appropriate velocity is complete on 4th kit no longer 5th bc at 5th the engine's rev isn't generating sufficient hp to bypass that quickly.
