$(30$ points$)$ Use SW FEA to apply an axial torque of $750in.lbf$ on the right end of the stepped

shaft. Determine stress concentration factor $K_t$ for torsion from your FEA. Provide a hardcopy

color plot of your FEA showing maximum von Mises stress. Note that you must convert von

Mises stress to shear stress in order to compute stress concentration factor per below.

$K_{t_{-}\text{t}\text{o}\text{r}\text{s}\text{i}\text{o}\text{n}}=\frac{{}_{FE{A}_t\text{o}\text{r}\text{s}\text{i}\text{o}\text{n}}}{{}_{NOMINA{L}_t\text{o}\text{r}\text{s}\text{i}\text{o}\text{n}}}$

$\frac{{}_{\text{F}\text{E}\text{A}}^{\text{'}}}{{}_{NOMINA{L}_t\text{o}\text{r}\text{s}\text{i}\text{o}\text{n}}}$
