45% 45° X Fig. 10 Fig. 12 11. A spherical tank has an inside diameter of 3.85 m. The tank is to contain gas at an internal pressure of 2.7 MPa. If the tangential stress is not to exceed 180 MPa, determine the minimum required thickness of the tank wall. 12. A typical aluminum-alloy scuba diving tank is shown in Fig. 12. The outside diameter of the tank is 200.6 mm. and the wall thickness is 12.6 mm. If the air in the tank is pressurized to 20,6 MPa, determine: (a) the longitudinal and hoop stresses in the wall of the tank. (b) the maximum shear stress in the plane of the cylinder wall. (c) the absolute maximum shear stress on the outer surface of the cylinder wall.
