For the cylindrical vessel with hemispherical ends (heads) under uniform internal pressure of intensity p = 500 psi shown in Figure P9–21, determine the maximum von Mises stress and where it is located. The material is ASTM—A242 quenched and tempered alloy steel. Use a factor of safety of 3 against yielding. The inner radius is a = 100 inches and the thickness t = 2 in.
