The four balls, each of mass m = 2.3 kg, are rigidly mounted to the rotating frame and shaft, which are initially rotating freely about the vertical z-axis at the angular rate of 19.5 rad/s clockwise when viewed from above. The distances r = 0.25 m and R = 0.52 m. If a constant torque M = 23.1 N-m is applied to the shaft, calculate the time t to reverse the direction of rotation and reach an angular velocity 0= 19.5 rad/s in the same sense as M.

A uniform, 0.0300 kg rod of length 0.400 m rotates in ahorizontal plane about a fixed axis through its center and perpendicularto the rod. Two small rings, each with mass 0.0200 kg, are mounted sothat they can slide without friction along the rod. They are initially heldby catches at positions 0.0500 m on each side of the center of the rod,and the system is rotating at 48.0 rev/min.

What is the angular speed (a) of the systemat the instant when the rings reach the ends of the rod; (b) of the rodafter the rings leave it?
