The horizontal beam $\mathrm{PQRS}$ shown in the figure has a fixed support at point $\mathrm{P}$, an internal hinge at point $Q$, and a pin support at point $R$. A concentrated vertically downward load $(V)$ of $10 \mathrm{kN}$ can act at any point over the entire length of the beam.
The maximum magnitude of the moment reaction (in $\mathrm{kN} . \mathrm{m}$ ) that can act at the support $\mathrm{P}$ due to $V$ is $\_\_\_\_\_\_$ (in integer).
