Problem $03\mathrm{.}134-$ Find the stresses on the inner and outer surface of a utility hook

A utility hook was formed from a round rod of diameter $d=14\mathrm{.}00mm$ into the geometry shown in the figure. Given: $F=9\mathrm{.}00kN,L=300\mathrm{.}0mm,$ and $D_i=52\mathrm{.}5mm.$

Problem $03\mathrm{.}134.$a $-$ Find the stress on the inner surface at section A$-$A

What is the stress at the inner surface AND outer surface at section $A-A?$

The stress at the inner surface is determined to be $k\frac{N}{m}{m}^2.($Round the final answer to three decimal places.$)$
