Question

A flywheel has a mass of 1400kg and a radius of gyration of 1.2m. When running at 300rev/min, the driving torque is removed, and the wheel comes to rest in 80seconds. Calculate the work done against friction per revolution, if it is constant throughout. Calculate also the frictional torque.
