A pressurized steel tank is constructed with a helical weld that makes an angle at = 55" with the longitudinal axis (see figure). The tank has radius r = 0.6 m, wall thickness t = 18 mm, and internal pressure p = 2.8 MPa. Also, the steel has modulus of elasticity E = 200 GPa and Poisson's ratio v = 0.30. Determine the following quantities for the cylindrical part of the tank.(a) The circumferential and longitudinal stresses.(b) The maximum in-plane and out-of-plane shear stresses.(c) The circumferential and longitudinal strains.(d) The normal and shear stresses acting on planes parallel and perpendicular to the weld (show these stresses on a properly oriented stress element

Pressure Vessels

The term pressure vessel refers to a closed container that contains gas or liquid at a different pressure than environment pressure. The pressure vessels have a wide scale of applications in our day-to-day lives and other industrial places. Some common examples of pressure vessels are gas cylinders, autoclaves, compressor vessels, etc.
