Problem 1.36 A steel pipe of 400-mm outer diameter is fabricated from 10-mm-thick plate by welding along a helix that forms an angle of 20° with a plane perpendicular to the axis of the pipe. Knowing that the maximum allow¬able normal and shearing stresses in the directions respectively normal and tangential to the weld are ? = 60 MPa and ? = 36 MPa, determine the magnitude P of the largest axial force that can be applied to the pipe.
