A thin-walled cylindrical steel water storage tank 30 ft in diameter and 60 ft long is oriented with its longitudinal axis vertical. The tank is topped with a hemispherical steel dome. The wall thickness of the tank and dome is 0.75 in. If the tank is pressurized to 50 psig and contains water 55 ft above its base, and considering the weight of the tank, determine the maximum state of stress in the tank and the corresponding principal stresses (normal and shear). The weight density of water is 62.4 lbf/ft3

Question

A thin-walled cylindrical steel water storage tank 30 ft in diameter and 60 ft long is oriented with its longitudinal axis
vertical. The tank is topped with a hemispherical steel dome. The wall thickness of the tank and dome is 0.75 in. If
the tank is pressurized to 50 psig and contains water 55 ft above its base, and considering the weight of the tank,
determine the maximum state of stress in the tank and the corresponding principal stresses (normal and shear). The
weight density of water is 62.4 lbf/ft3
