Torque and Force

  1. Nov 8, 2006 #1
    (a) Give an example in which the net force acting on an object is zero and yet the net torque is nonzero.


    (b) Give an example in which the net torque acting on an object is zero and yet the net force is nonzero.

    can b be torque= Tension(12 N)(radius 0m) ?

    (a) any two parallel forces with the same magnitude and opposite directions form a torque, while the net force is obvoiusly zero.

    (b) consider an object sliding down an incline.

    Remember that two parallel forces with the same magnitude and opposite directions have to be separated by some distance to produce a torque. These are commonly called a 'couple'.
