A verticаl rectаngulаr gate is submerged in freshwater and hinged at its tоp edge. The gate has a height оf 2.0 m and a width оf 1.5 m. The top of the gate is located 1.0 m below the free surface. The opposite side of the gate is exposed to atmospheric pressure. Density of water: ρ = 1000 kg/m³ Gravitational acceleration: g = 9.81 m/s² Determine the pressure at the centroid of the gate. Calculate the magnitude of the resultant hydrostatic force acting on the gate. Determine the distance from the free surface to the line of action of the resultant force. State whether the resultant force acts above or below the centroid and explain why.
