The pressure vessel shown below is being lifted by two cables that are attached to the bottom of the tank at points L = 6' away from each other. Assume that this causes reaction forces at the bottom of the tank that are oriented in the direction of the cable, i.e. 30 degrees from vertical. The tank weighs 4,970 lb. For simplicity, assume that the weight is evenly distributed from one connection point to the other, thus ignoring any weight in the end caps. Also assume that the tank is pressurized to 272 psi. The tank has an internal radius of 1.7 ft and a thickness of 1/8 inch. The tank is made out of steel with a 50 ksi yield strength. Determine 1) the combined stress state at point C, which is located at mid-length at the bottom of the tank and 2) the factor of safety against yielding at point C using the Tresca criterion. be sure to clearly indicate your answers to parts 1 and 2.
