A rectangular gate of length $L$ and width $b$ holds water on one side. Atmospheric

air is on the other side. It is held at an angle $$ from the vertical. The water has

density $$ and wets three quarters of the length $L.$ The gravity constant is $g.$ The

hinge is on the very middle of the length $L.$ Express both $F_R$ and $T$ in terms of

given parameters, and tell if the torque is into or out of$,$ the paper.
