(b) A T-shape pendulum hinged at O with a total of mass

(b) A T-shape pendulum hinged at O with a total of mass 1.2 kg may carry two small spheres attached at its ends in a vertical plane as shown in Figure Q4(b). The system is released from rest at the position 0 = 50 and the mass of the spheres is negligible. At the instant immediately after being released, (i) draw the complete free-body and kinetic diagrams of the pendulum, and (ii) determine the resulting angular acceleration of the pendulum and the corresponding dynamic reaction at hinge O. Hint: consider the T-shape pendulum to be made of thin rods OA and BC. 2.0 m 1.0 m 1.0 m B
