A spherical gas container made of steel has a(n) 20-ft outer diameter and a wall
A spherical gas container made of steel has a(n) 20-ft outer diameter and a wall thickness of 0.375 in. Knowing that the internal pressure is 60 psi, determine the maximum normal stress and the maximum shearing stress in the container. The maximum normal stress in the container is ksi, and the maximum shearing stress in the container is ksi.
