The AISC Shape $\backslash (\backslash$mathrm$\{$C$\}230\backslash$times $30\backslash )$ section shown in Figure $2$ below carries a bending moment, M $,$ of magnitude $1800$ Nkm acting at $\backslash (20^\{\backslash$circ$\}\backslash )$ to the horizontal as indicated.

Determine:

$2\mathrm{.}1)$ the angle, $\backslash (\backslash$alpha $\backslash ),$ between the neutral axis and the horizontal

$2\mathrm{.}2)$ the maximum bending stress acting on the cross section.
