What is the relationship between Torque and Energy?

[Rising_Hg]

I was reading about Torque on Wikipedia (http://en.wikipedia.org/wiki/Torque" ).

There was this relation given :

Energy = Torque * Angle covered.
Can anybody explain me how or show the derivation ?

- Rising_Hg

i didnt even know that relation existed but i can give it a shot.

Energy is force x distance. So you have torque, which is force multiplied by radius. radius multiplied by angle covered is going to be a distance. So there is force x distance. which is energy.

Yep, that's it.

Perhaps the OP is not familiar with radian angle measurement. Is this the case Rising_Hg?
