A cylindrical pipe of 160-mm outside diameter and 10-mm thickness, spirally welded at an angle of o = 40 with the axial (x) direction, is subjected to an axial compressive load of P-150 kN through the rigid end plates (Fig. P1.10). Determine the normal o and shearing stresses Tr'y acting simultaneously in the plane of the weld. Weld FIGURE P1.10.
