Question: 260 mm the 2kg disk d is attached to arm...

Question details

260 mm The 2-kg disk d is attached to arm BC The moment M = {4exp(0.2t); N-m is applied at C, where t is the time is seconds. Find the angular velocity of BC, 2 seconds after starting from rest, assuming that (a) The disk is fixed to shafl BC (b) The disk has an initial freely spinning angular velocity of (-50k) rad/s, prior to the application of the torque. 50 mm
