The gas storage tank is fabricated by bolting together two half cylindrical thin shells and two hemispherical shells as shown. If the tank is designed to withstand a pressure of \(3 \mathrm{MPa}\), determine the required minimum thickness of the cylindrical and hemispherical shells and the minimum required number of bolts for each hemispherical cap. The tank and the 25 -mm-diameter bolts are made from material having an allowable normal stress of \(150 \mathrm{MPa}\) and \(250 \mathrm{MPa}\), respectively.The tank has an inner diameter of \(4 \mathrm{~m}\).
