Determine the normal stress in a ball, which has an outside diameter of 220 mm and a wall thickness of 3 mm, when the ball is inflated to a gage pressure of 110 kPa.
A typical aluminum‐alloy scuba diving tank is shown. The outside diameter of the tank is 200 mm and the wall thickness is 12 mm. If the air in the tank is pressurized to 20 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.
A closed cylindrical tank containing a pressurized fluid has an inside diameter of 250 mm and a wall thickness of 10 mm. The stresses in the wall of the tank acting on a rotated element have the values are shown. Determine the fluid pressure.
