Chapter 1, Problem 1.35(choose chapter or problem)
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 \(20^{\circ}\) with a plane perpendicular to the axis of the pipe. Knowing that a 300-kN axial force P is applied to the pipe, determine the normal and shearing stresses in directions respectively normal and tangential to the weld.

QUESTION:
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 \(20^{\circ}\) with a plane perpendicular to the axis of the pipe. Knowing that a 300-kN axial force P is applied to the pipe, determine the normal and shearing stresses in directions respectively normal and tangential to the weld.
ANSWER:
Step 1 of 5
For the given load P we have to determine the normal and shearing stress on the inclined plane. We will first calculate the cross-sectional area of the pipe and then compute the resulting stresses using the appropriate stress formulas.
Given data are
Outer diameter of pipe:
Outer radius of pipe,
Inner radius of piper
Inclination of shearing plane
