Consider the pipe structure shown to the right, and

answer the following questions.

Notes for Clarification:

We are analyzing a cross section perpendicular to

the lower pipe's long axis at points C and D$.$

$***$ Point D is at the outer pipe surface in a tangent

plane orthogonal to the z axis.

$***$ Point C is at the outer pipe surface in a tangent

plane orthogonal to the y axis.

Known parameters are r $($outer radius,$)$ t $($total wall

thickness,$)$ A$,$I,J$,$E$,$Q$,$ and G$.$ Answer using these

parameters unless numerical values are given.

Assume weight is negligible.

what would be the expression for normal stress and shear stress at points a$,$ b$,$ c$,$ and d
