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 cylinder B and the horizontal surface is 0.2 and that no slipping occurs between the cylinders, determine (a) the angular acceleration of each cylinder, (b) the minimum allowable value of the coefficient of static friction between the cylinders.
