$-$ Step $1$: Draw the FBD$,$ and shear and moment diagram to determine the maximum moment. Label all points where the diagram changes.

Can use either graphical method or by finding internal loading as a function of position

$-$ Step $2$: Given b$=150$ mm and $\backslash (\backslash$mathrm$\{$h$\}=\backslash$mathbf$\{300\}\backslash$mathrm$\{$mm$\}\backslash ),$ Find centroid and Moment of Inertia

$-$ Step $3$: Find maximum stress using flexure formula based on the maximum moment

$-$ Bonus: Draw stress distribution $($show compression and tension arrows and stress values$)-$ Step $1$: Draw the FBD and shear diagram on provided lines to determine the maximum shear. Label all points where the diagram changes.

Can use either graphical method or by finding internal loading as a function of position

$-$ Step $2$: Given cross section shown, find centroid and Q $($needed to find shear stress at point C$)$

$-$ Bonus: Find moment of Inertia and maximum shear stress at point C
