Find the magnitude and location of the resultant hydrostatic force on the gate shown in Figure 2.73. Also find the magnitude of the moment about axis XX that would be required to open the gate. The pressure above the water surface is equal to atmospheric pressure, as is the pressure on the other side of the gate.
