The 0.5-lb ball is guided along the vertical circular path r = 2rc cos u using the arm OA. If the arm has an angular velocity u . = 0.4 rad>s and an angular acceleration u $ = 0.8 rad>s 2 at the instant u = 30, determine the force of the arm on the ball. Neglect friction and the size of the ball. Set rc = 0.4 ft
