In each of the gates shown, the top of the gate is supported by a frictionless hinge. Each has a rectangular overhang that sticks out or in a distance a from the gate (a is small relative to the depth h). A stop at the bottom of each wall prevents it from opening in a counterclockwise direction. When the water is at the same depth h in both cases, what is the ratio of the horizontal force exerted on stop
(a) to the horizontal force exerted on stop
(b) Please draw appropriate FBDs.
