The 4-lb uniform slender rod AB, the 8-lb uniform slender rod BF, and the 4-lb uniform thin

Question:

The 4-lb uniform slender rod AB, the 8-lb uniform slender rod BF, and the 4-lb uniform thin sleeve CE are connected as shown and move without friction in a vertical plane. The motion of the linkage is controlled by the couple M applied to rod AB. Knowing that at the instant shown the angular velocity of rod AB is 15 rad/s and the magnitude of the couple M is 5 ft ??lb, determine

(a) The angular acceleration of rod AB,

(b) The reaction at point D.
