Question: A 4-kg uniform slender rod AB is held in position by two ropes and the link CA which has a negligible weight. After rope BD

A 4-kg uniform slender rod AB is held in position by two ropes and the link CA which has a negligible weight. After rope BD is cut the assembly rotates in a vertical plane under the combined effect of gravity and a couple M applied to link CA as shown. Knowing that the magnitude of the acceleration of rod AB is 4 m/s2 immediately after rope BD has been cut, determine

(a) The magnitude of the couple M,

(b) The tension in rope EB.
