A person drops a cylindrical steel bar Y 5 00 10 0 Pa from a height of 4 70 m distance between the floor and the bottom of the vertically oriented bar The bar of length L 0 870 m radius R 0 00700 m and mass m 1 400 kg hits the floor and bounces up maintaining its vertical orientation Assuming that the collision with the floor is elastic and that no rotation occurs what is the maximum compression Al of the bar Use the gravitational acceleration g 9 81 m s
