A beam having a T$-$shaped cross section $($see Fig. below$)$ is subjected to a vertical shear force $V=150kN.$

Determine the shear stress at the top of the web and the maximum shear stress $($Disregard the areas of the fillets.$).$

tweb $=52\mathrm{.}12$MPa,$NA=65\mathrm{.}31$MPa

$web=49\mathrm{.}33$MPa,$NA=55\mathrm{.}88$MPa

$web=62\mathrm{.}22$MPa,$NA=65\mathrm{.}31$MPa

$web=42\mathrm{.}00$MPa,$NA=45\mathrm{.}18$MPa

$$web$=72\mathrm{.}22$ MPa, $NA=75\mathrm{.}08$MPa
