Two identical 16-lb uniform cylinders of radius r = 4 in. are at rest when a couple M of constant magnitude 4 lb·ft is applied to cylinder A. Slipping occurs between the two cylinders and between cylinder B and the horizontal surface. Knowing that the coefficient of kinetic friction is 0.5 between the two cylinders and 0.2 between cylinder B and the horizontal surface, determine the angular velocity of each cylinder after 5 s.
