A person drops a cylindrical steel bar ( Y=6.00×1010 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=0.720 m , radius R=0.00650 m , and mass m=1.100 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 Δ of the bar? Use the gravitational acceleration g=9.81 m/s2.
