Problem $2$: Pressure force on a triangular gate

As shown in figure $2,$ a planar gate of right$-$angled triangular shape is installed on an inclined wall at

$=60$ angle from the horizontal surface, supporting water with density $=1000k\frac{g}{m^3}.$ The $y-$

coordinate is defined along the inclined wall and $x-$coordinate is perpendicular to the page.

Find the magnitude of the resultant force, $F_R,$ and the $y-$location of its action, $y_R($no need to report

$x_R).$ Report your $F_R$ in Newton and $y_R$ in meter. $(2$ pts$)$

Find the stopper force $F_s$ acting horizontally at the the tip of the triangular gate in order to hold

the gate closed. $(1$ pt
