Problem $07\mathrm{.}048-$ Combined loading: determine principal stresses and maximum shear stress using Mohr's circle.

The 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, determine the principal stresses and the maximum shearing stress at point $K$ using Mohr's circle. $($Round the final answers to one decimal place.$)$

Given: $F=15\mathrm{.}5kN$

The principal stresses are ${}_{\text{m}\text{a}\text{x}}=$ MPa and ${}_{\text{m}\text{i}\text{n}}=|$ MPa $(+$ tensile; $-$ compressive$).$

$$

The maximum shearing stress magnitude is $$ MPa $.$
