Two identical 16-lb uniform cylinders are at rest when a constant couple M of magnitude 3 ft · lb is applied to cylinder A. Knowing that the coefficient of kinetic friction between the cylinders is 0.45 and the coefficient of kinetic friction between cylinder B and the horizontal surface is 0.15, determine the angular acceleration of each cylinder.
