SITUATION 5. A triangular gate of height 1.2 m and base 0.9 m is installed in a position that its plane is inclined 60 degrees with the horizontal with its vertex at the top and the base is parallel to the water surface. The vertex is at a depth of 2 m vertically below the water surface. Fresh water is on one side of the gate. 12. Evaluate the total hydrostatic force on the gate in kN. a. 14.3 kN b. 18.2 kN c. 12.4 KN d. 13.8 kN 13. Locate the point of action of the total hydrostatic force from the vertex on the plane of the gate. a. 0.8329 m b. 0.8732 m c. 0.8257 m d. 0.8572 m 14. If the gate is hinged at the bottom, evaluate the force normal to the gate at its vertex that will be required to open it. a. 3.43 KN b. 4.45 kN c. 5.32 KN d. 3.85 kN
