$($a$)$ In Assignment $2,$ we found the location of the centroid $\text{'}C\text{'}$ of this section to

be:

$\frac{?}{\text{b}\text{a}\text{r}}(z)=61\mathrm{.}6mm$;$\frac{,}{b}ar(y)=80\mathrm{.}68mm$

Determine the new principal centroidal axes $($PCA$\text{'}$s$)$ of this section. Clearly

illustrate the $I_{\text{m}\text{i}\text{n}}$ and $I_{\text{m}\text{a}\text{x}}$ axes, and the angle of orientation on an

appropriate sketch of the section.

$($b$)$ For the given orientation of the moment, determine the position of the

neutral axis.

$($c$)$ Determine the stress at points A and $B.$
