Question:
Two identical 4-lb slender rods AB and BC are connected by a pin at B and by the cord AC. The assembly rotates in a vertical plane under the combined effect of gravity and a couple M applied to rod AB. Knowing that in the position shown the angular velocity of the assembly is zero and the tension in cord AC is 0.45 lb, determine
(a) The angular acceleration of the assembly,
(b) The magnitude of the couple M.
