The rotary screen S is used to wash limestone. When empty it has a mass of 800 kg and a radius of gyration of k_G = 1.75 m. Rotation is achieved by applying a torque of M = 280 N · m about the drive wheel at A. If no slipping occurs at A and the supporting wheel at B is free to roll, determine the angular velocity of the screen after it has rotated 5 revolutions. Neglect the mass of A and B.
