A vertical triangular plane gate with a base of 3 m and a height of 5 m is submerged at a depth 4 m in water open to the atmosphere, as illustrated in Figure ECP 2.140. (a) Determine the magnitude of the resultant hydrostatic force acting on the vertical triangular plane gate. (b) Determine the location of the resultant hydrostatic force acting on the vertical triangular plane gate.
