The gate shown in the figure is used to contain the water in a reservoir. The gate is hinged at B which is located at a depth of 4 ft. from the free surface of water (h1). Under the closed configuration, the gate leans on the floor of the reservoir as shown. The gate is 20 ft wide (in the direction perpendicular to the page), 25 ft long and has a mass of 600 lbm. Atmospheric pressure is 14.7 psia and density of water is 62.4 lbm/ft³. Determine the minimum force (F) required to open the gate if it is applied at the center as shown. h1 В Water h2 45°
