Question: The 0.5-lb ball is guided along the vertical circular path r = 2rcosθ using the arm OA. If the arm has an angular velocity θ = 0.4 rad/s and an acceleration θ = 0.8 rad/s² at the instant θ = 30, determine the force of the arm on the ball. Neglect friction and the size of the ball. Set rc = 0.4 ft.
