The steel pressure tank shown has a 30-in. inner diameter and a 0.375-in. wall thickness. It is given that the butt-welded seams form an angle β = 50° with the longitudinal axis of the tank and that the gage pressure in the tank is 200 psi. Determine the normal stress perpendicular to the weld. Determine the shearing stress parallel to the weld.

Question

The steel pressure tank shown has a 30-in. inner diameter and a 0.375-in. wall thickness. It is given that the butt-welded seams form an angle β = 50° with the longitudinal axis of the tank and that the gage pressure in the tank is 200 psi.

Determine the normal stress perpendicular to the weld.

Determine the shearing stress parallel to the weld.

The image shows a cylindrical object with helical grooves, resembling threads or a spiral pattern wrapped around the cylinder. A line is drawn perpendicular to the axis of the cylinder intersecting one of the grooves, and an angle \(\beta\) is indicated between the line and the groove. The grooves wrap consistently around the cylinder, suggesting a screw thread or helical structure. This angle \(\beta\) is often known as the "helix angle," which is a key parameter in the design and function of threaded components.
