The 4-m-diameter circular gate of Fig. E2.6a is located in the inclined wall of a large reser- XAMPLE voir containing water (y = 9.80 kN/m³). The gate is mounted on a shaft along its horizon- tal diameter. For a water depth of 10 m above the shaft determine: (a) the magnitude and lo- cation of the resultant force exerted on the gate by the water, and (b) the moment that would have to be applied to the shaft to open the gate. 10 m Shaft Stop m 60° 0 บ (b) (c) Center of pressure (a) FIGURE E2.6 M
