The 16-lb sphere and 11-lb block (shown in section) are secured to the arm of negligible mass which rotates in the vertical plane about a horizontal axis at O. The 5-lb plug is released from rest at A and falls into the recess in the block when the arm has reached the horizontal position. An instant before engagement, the arm has an angular velocity wo 1.8 rad/s. Determine the angular velocity w (positive if counterclockwise, negative if clockwise) of the arm immediately after the plug has wedged itself in the block. 16 lb Answer: w 18" 5 lb 22" 11 lb. rad/s

Question
The 16-lb sphere and 11-lb block (shown in section) are secured to the arm of negligible mass which rotates in the vertical plane about
a horizontal axis at O. The 5-lb plug is released from rest at A and falls into the recess in the block when the arm has reached the
horizontal position. An instant before engagement, the arm has an angular velocity wo 1.8 rad/s. Determine the angular velocity w
(positive if counterclockwise, negative if clockwise) of the arm immediately after the plug has wedged itself in the block.
