A 3-m-high, 11-m-wide rectangular gate is hinged at the top edge at A and is restrained by a fixed ridge at B. Determine the hydrostatic force exerted on the gate by the 5-m-high water and the location of the pressure center. Take the density of water to be 1000 kg/m3 throughout. The hydrostatic force exerted on the gate by the water is kN. The vertical distance of the pressure center from the free surface of water is m..
