A person drops a cylindrical steel bar (Y = 8.00 × 1010 Pa) froma height of 3.20 m (distance between the floor and the bottom ofthe vertically oriented bar). The bar, of length L = 0.820 m,radius R = 0.00500 m, and mass m = 1.300 kg, hits the floor andbounces up, maintaining its vertical orientation. Assuming thecollision with the floor is elastic, and that no rotation occurs,what is the maximum compression of the bar?
