(b) What is the maximum shear stress rm2Xin the wall of the tank?
(c) What is the maximum normal strain e in the wall? (For steel, assume E = 30 X 10 psi and v = 0.29.)

Problem A-1 [Pressure Vessel Problem]
A welded cylindrical pressure vessel is shown in the figure.
The inner diameter is 600 mm. The wall thickness is 10 mm.
Given the gage pressure of 5 MPa, determine (1) the normal
stress perpendicular to the weld line and (2) the shear stress
parallel to the weld line.
Weld Line
30°
The dimensions of the compressed air tank manufactured in the form of a cylinder are given in the figure. The tank is manufactured by joining a 6 mm thick steel plate with a helical weld at an angle of 30°. Since the safe shear stress in the direction parallel to the weld seam is 30 MPa, calculate the maximum pressure that can be used in the tank.
A compressed air tank has an inner diameter of 0.45 metre, and a wall
thickness of 6.35 mm. It is formed by welding two steel hemispheres.
i. if the allowable tensile stress is 96 MPa, what is the maximum
permissible air pressure (pa) in the tank.
ii. if the allowable shear stress in the steel is 40 MPa, what is the
maximum permissible air pressure (pb) in the tank?
