Homework Statement
Calculate the work done on a solid cylinder of mass 5.0 kg and radius 55.6 cm by an applied force of 12.2N if it turns 45 degrees.
Homework Equations
W = torque x angle (radians)
The Attempt at a Solution
I just used:
W = torque x angle
= Force x perpendicular radius x angle
= 12.2 x 55.6 x pi/4
Why is this wrong? I think it's wrong, because part b of the question asks how the answer would change if the object was a ring.
