- Homework Statement
- Determine the normal and shear stresses developed at the points of interest.

- Relevant Equations
- Strength of Materials

Normal Stress ##\sigma##:

## \sigma = \frac{F}{A}## - tensile/compressive

##\sigma = \frac{Mr}{I}## - bending

Shear Stress ##\tau##:

## \tau = \frac{Tr}{J}## - Torsion

## \tau = \frac{QV}{It}## -Shear Flow

Here is my combined loading:

The book solution for normal and shear stresses respectively are:

a) ##20.4~\text{MPa}, 14.34 ~\text{MPa} ## - I find both

b) ##-21.5~\text{MPa}, \boxed{19.98~\text{MPa}}## - I find the normal stress, but I'm not getting the book answer for the shear stress.

I'm getting Torsion + Shear Flow ##\approx 25.6 \text{MPa}##

I'm just brushing up for the heck of it...No professor to ask. Does anyone get solution in the book?
