A structural member with a T$-$section cross$-$section has a length of $2050$ mm and is rigidly fixed at each end.

If a force $\backslash ($ F$=1\mathrm{.}5\backslash$mathrm$\{$kN$\}\backslash )$ is applied at a distance of $375$ mm from the left end, what is the magnitude of the reaction moment at the support on the left side $($in units of Nm$\backslash ()\backslash )?$
