1) Use SolidWorks (SW) FEA to apply a bending load of 220 lbf on the right end of the stepped
shaft as shown below. This is the same geometry as Homework 1 and the same geometry and
bending load as notes "n05_static.docx". Determine stress concentration factor Kt for bending
from your FEA. Provide a hardcopy color plot of your FEA showing maximum von Mises
stress.

choice
K t _ bending   FEA _ bending /  NOMINAL _ bending
L = 0.75 in
K t _ bending _______________
d = 0.5 in
D = 0.75 in
r = 0.05 in
SAE 1045 cold-rolled steel
2) Use SW FEA to apply an axial torque of 157.6 in.lbf on the right end of the stepped shaft.
This is the same geometry and torsional load as notes "n05_static.docx". Determine stress
concentration factor Kt 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 _ torsion   FEA _ torsion /  NOMINAL _ torsion  ' FEA /  NOMINAL _ torsion
K t _ torsion _______________
