Problem $9(10$ points$)$

Consider the beam in the figure below has the same cross$-$section as Problem $8.$

Draw the shear and moment diagrams

What is the magnitude of the peak moment in the beam and where does it act?

If the peak moment is oriented about the $?\text{'}$ axis $($on Problem $8),$ what is the peak axial stress in

the beam in MPa?

Where is the peak stress located $($top or bottom of the beam$)?$

Is the peak stress tensile or compressive?

Note: $1lb=4\mathrm{.}448N$;$1ft=0\mathrm{.}3048m$

$($The figure in Problem $8$ is in the correct view of the beam cross$-$section$)$
