A structural member with a hollow rectangular cross$-$section has a length of $1025$ mm and is rigidly fixed at each end.

If a force

$F=76500$

$N$ is applied at a distance of $225$ mm from the right end, what is the reaction force at the support on the right side $($in units of N $)?$

NOTE: upward reactions, as shown, should be entered as positive values and downward forces as negative values.
