Question:

Two identical 6-lb uniform rods are hinged at point B and attached to a spring of constant k = 23lb/in. The rods are guided by small wheels of negligible weight and the system is in equilibrium when the rods are horizontal as shown. Knowing that point B is depressed 0.8 in. and released, determine

(a) The frequency of the resulting vibration,

(b) The magnitude of the maximum angular acceleration of rod AB.
