The design life of the rigid pavement for drainage coefficient 0.6 and 0.8 .

Question

337 kN -Weld -25° 6 mm 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.
