HW8 A shaft fitted with a flywheel rotates at 650 r.p.m. and drives a machine. The torque of machine varies in a cyclic manner over a period of 2 revolutions. The torque rises from 650 N-m to 2200 N-m uniformly during 110° and remains constant for the following 270°. It then falls uniformly to 600 N-m during the next 100° and remains constant for the end cycle, the cycle being repeated thereafter. Determine the power required to drive the machine and percentage fluctuation in speed, if the driving torque applied to the shaft is constant and the mass of the flywheel is 180 kg with radius of gyration of 35 cm.
