Q3) A grinding machine abrasive wheel has mass of 40 kg rotates at 2000 r.p.m. There is a sudden power outage. After 80 seconds later the wheel speed falls to 1200 r.p.m. The frictional resistive torque against the wheel speed is 20 Nm. Calculate, a) Moment of Inertia of wheel. b) Radius of gyration of wheel. c) Total time taken to come to rest. 5.0 2.0 3.0 Q3) A grinding machine abrasive wheel has mass of 40 kg rotates at 2000 r.p.m. There is a sudden power outage.
