A $L=5-m$ high, $W=5-m$ wide rectangular plate blocks the end of a freshwater channel,

to depth $H.$ The plate is hinged about a horizontal axis along its upper edge through a

point A and is restrained from opening by a fixed ridge at point B$.$ Determine the forces

at A and B to be exerted on the plate. The will depend on $H.$ First solve analytically.

Use a code package $($MATLAB$/$Python$/$Excel$)$ to plot $F_A$ and $F_B$ vs $H$ on the same

graph
