13-9. The gas steorage tank is fabricuted by bolting togeth- er two half cylindrical thin shells and two hemispherical shells as shown. If the tank is designed ta withstand a pres- sure of 3 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 narmal stress of 150 MPa and 250 MPa, respectively. The tank has an inner diameter of 4 m.
