The flywheel is rotating with an angular velocity at time t = 0 when a torque is applied to increase its angular velocity . If the torque is controlled so that the angle between the total acceleration of point A on the rim and the radial line to A remains constant, determine the angular velocity and the angular acceleration as functions of the time t.
