Torque - Energy relation

  1. Feb 2, 2010 #1
    I was reading about Torque on Wikipedia (http://en.wikipedia.org/wiki/Torque" [Broken]).

    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?
