Modified problem from textbook:

a$.$ Copy the drawing and mark on it the

location of highest bending stress. Create a

$3$D Mohr circle representation of the

stresses at this point. Note the stresses at

this location could include both normal and

shear stresses. Do not neglect transverse

shear stresses.

b$.$ Mark on the drawing the location of highest

combined torsional and transverse shear

stress. Create a $3$D Mohr circle

representation of the stresses at this point.

Note the stresses could include both normal

and shear stresses.
