A T$-$beam $($long and cross section$)$ is shown in the following figure with two concentrated loads.

$($a$)$ Draw shear force and bending moment diagrams. $[3+3]$

$($b$)$ Determine the maximum shear stress in the beam at location of the glued joint at $"$C$"$ between flange and web, shown in the cross section of the beam. $[3+3]$
