A motor equipped with a flywheel has to supply a load torque of 600 N-m for 10sec followed by a no-load period long enough for the flywheel to regain it’s full -speed. It is desired to limit he motor torque to 450 N-m .Assume the motor speed torque characteristics to be a straight line in the range of operation. Motor has an inertia of 10 Kg-m 2. Calculate Moment of inertia of flywheel.
