Problem $3$: $(20$ Points$)$

A beam is loaded as shown, and the Shear Force diagram is given. The location of the centroid of the Tee$-$Section is given and $I_{c-c}=1\mathrm{.}42i{n}^4.$

$($i$)$ Find the Shearing stress at point A $($located in web$),$ for section at C$.(10$ points$)$

$($ii$)$ Find the absolute maximum Shearing Stress in the beam. $(10$ points$)$
