A machine requires a torque of (5000 + 500 sine) Nm to drive it, where 0 is the angle of
rolalion. The machine is direcly coupled to any engine which produces a lorque of (5000 + 600
sin20) Nm. The flywheel has a mass of 500 kg at a radius of gyration of 0.4 m. If the mean
speed is 15 rad/s, then the total percentage fluctuation of speed is
fluctuation of energy occurs between 180° and 300° angular position approximately)
