Figure below shows a hand crank with static vertical load applied to the handle. Using the Mohr circle approach to determine the principal stresses and absolute maximum shear stresses at the root of $25$ mm diameter rod $($ignore curved beam stress concentration effects$)$

$($a$)$ at the top surface location, a

$($b$)$ at the $3$ o'clock surface location, b

To compare the results of hand calculation, you are required to conduct a FEA using NX $($see instruction video posted on Canvas$).$ The CAD model is provided. You are required to present the FEA result $($cut and paste$)$ at the point a and $b$ with the maximum and minimum principal stresses, ${}_1$ and ${}_3.$

Use material mechanical properties: $E=210$GPa and $v=0\mathrm{.}28$
