PROBLEM 1.33
A steel pipe of 300 mm outer diameter is fabricated from 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 the maximum
allowable normal and shearing stresses in directions respectively
normal and tangential to the weld are σ = 50 MPa and 7 = 30 MPa,
determine the magnitude P of the largest axial force that can be applied
to the pipe.
