A flywheel of mass 183 kg has an effective radius of 0.63 m (assume the mass is concentrated along a circumference located at the effective radius of the flywheel). (a) What torque is required to bring this wheel from rest to a speed of 120 rpm in a time interval of 34.3 s? (b) How much work is done during the 34.3 s? Alright I figured out (a) using the moment of Inertia and the angular acceleration to be 26.65 N * m So for part (b) I tried using W = torque * theta to find theta i used many ways all coming up with right around 432 rad so W = 26.65 * 432 = 11.5 kj But this answer isn't correct any suggestions as to where i went wrong??
