A sluice gate consisting of a quadrant of a circle is ,as shown in figure, used to stop the sea water. Calculate the magnitude and direction of the resultant force(Fr) on the gate due to sea water of specific gravity 1.025 and the turning moment required to open the gate. The width of the gate is 4m and it has a mass of 8000 kg
