The mass center, G. of the 2-b ball has a velocity of (vch - 5 t/s when it strikes the end of the smooth 4-lb slender bar, which is at rest. The bar has a length l-Sit and h- 0.5t. The coefficient of restitution is e-0.8. The goal is to find the angular velocity of the bar after impact. Step 1: Find the mass moment of inertia of the bar about O in slug.ft?. Give your answer with 3 decimals.
The 8-lb sphere and 6-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 4-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 = 2.2 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. 8 lb Answer: w= 12" i 100 20" 4 lb A 23" 6 lb rad/s

Q3. Consider two disks in essentially the same plane, and rotating about the common center O with different but constant angular velocities. Let the angular velocities by w and w'. The radii of the disks are r and r'. Two points P and P' are located at the outer edges of the disks. Assume that point O is fixed. Find the velocity and acceleration of P' relative to P at the time instant when the two points have the least separation, in the following two cases: (a) the observer is fixed to the ground, or nonrotating; (b) the observer is rotating with the unprimed system, i.e., the disk with radius r and angular velocity w. Express the results in terms of the unit vectors e; and en which rotate with the unprimed system. (Problem 2-15 in the text).
How can angular velocity be determined by angular displacement?
The center of the cylinder is moving to the left with constant velocity vo. Determine the angular velocity and the angular acceler- ation a of the bar. Neglect the thickness of the bar.
