HW-11 The smooth 2-kg cylinder C in Fig. 13-20a has a pin P through its center which passes through the slot in arm OA. If the arm is forced to rotate in the vertical plane at a constant rate = 0.5 rad/s, determine the force that the arm exerts on the peg at the instant 0 = 60°. 0.4 m Fig. 13-20a 0 -0.5 rad/s
