Chapter 8, Problem 8.2.9P
A spherical tank of diameter 48 in. and wall thickness 1.75 in. contains compressed air at a pressure of 2200 psi. The tank is constructed of two hemispheres joined by a welded seam (see figure).
(a) What is the tensile load/ (lb per in. of length of weld) carried by the weld?
(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.
Q2: A cirrular shaft. (50 mm) in diameter, is weldad to support by means ofcirrumferential
