A pressure vessel of 250-mm inner diameter and 6-mm wall thickness is fabricated from a 1.2- m section of spirally welded pipe AB and is equipped with two rigid end plates. The gage pressure inside the vessel is 2 MPa, and 45-kN centric axial forces P and P' are applied to the end plates. Determine (a) the normal stress perpendicular to the weld, (b) the shearing stress parallel to the weld. Fig. P7.120 1.2 m. 35 B Figure 2: Beer, Johnston, DeWolf, Mazurek.
