- 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.arrow_forwardThe 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/sarrow_forwardt с 6.

- 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.
