Problem $1$

A vertical steel pipe $AB$ has a $102-$mm outer diameter and a $6-$mm wall thickness. Knowing that arm CD is rigidly attached to the pipe, calculate and show $($using FDB and stess element$)$ the stress tensor step by step corresponding to points H and K$.$ Solve in SI and report

the results as integer numbers.

Answer: stress tensors below. Please provide step by step solutions along with the FBD and stress element for each point $($H and K$)$

${}_H$:$=\left[\begin{array}{ccc}0& 35& 0\\ 35& 0& 0\\ 0& 0& 0\end{array}\right]$MPa,${}_K$:$=\left[\begin{array}{ccc}0& 0& 0\\ 0& -37& -24\\ 0& -24& 0\end{array}\right]$
