Unformatted text preview: 1.35 A steel pipe of 300— mm outer diameter is fabricated lion: 6— mm- thick plate by welding along a helix which forms an angle of 25 ° with a plane perpendicular to the axis .. of the pipe. Knowing that a 250- kN axial force P is applied to the pipe, determine the I 1, normal and shearing stresses in directions respectively normal and tangential to the weld.
