Determine the speed v of the 50-Mg mass when it is just
Chapter 14, Problem 14-44(choose chapter or problem)
Determine the speed v of the 50-Mg mass when it is just over the top of the steel post, if after impact, the maximun stress developed in the post is 550 MPa. The post has a length of L = 1 m and a cross-sectional area of \(0.01 \mathrm{m}^{2}\). \(E_{\mathrm{st}}=200 \mathrm{GPa}, \sigma_{Y}=600 \mathrm{MPa}\).
