Question

(a) An 8 kg flywheel of radius r is initially at rest. Assume the radius of gyration k 0.12 m and the radius of the flywheelan 8kg flywheel of radius r is initially at rest. assume the radius of the gyration kG= 0.12m and the radius of the flywheel r = 0.125m. an object B also of mass 8 kg is attached to a cord that is wrapped around a periphery of the flywheel. the fly wheel starts to rotate clockwise with angular velocity. the rotation is resisted by a constant frictional torque mf in the bearing 1Nm. use the work energy principle to determine the flywheel angular speed after it has rotated through π/2 radians
