Ex) A vertical dam has a semicircular gate as shown in the figure. The total depth

*d*of the figure is 36 m, the height

*h*of air above the water level is 6 m, and the width

*w*of the gate is 10 m. Find the hydrostatic force against the gate. (Round your answer to the nearest whole number. Use 9.8 m/s^2 for the acceleration due to gravity. Recall that the weight density of water is 1000 kg/m^3.)
