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

Determine the moment of inertia of the cross$-$section respect to neutral axis!

$lz=4\mathrm{.}90*{10}^{7}m{m}^4$

$Iz=4\mathrm{.}07*{10}^{7}m{m}^4$

$lz=8\mathrm{.}88*{10}^{7}m{m}^4$

$lz=7\mathrm{.}47*{10}^{7}m{m}^{{?}^{?}}4$

$Iz=6\mathrm{.}97*{10}^{7}m{m}^4$
