A triangular gate of height 1.2m and base 0.9m 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 2m vertically below the water surface. Fresh water is on one slide of the gate. A. Evaluate the total hydrostatics force on the gate in kN. B. Locate the point of action of the total hydrostatic force from the vertex on the plane of the gate in m. C. 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 in kN.

Transcribed Image Text:A triangular gate of height 1.2m and base 0.9m 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 2m vertically below
the water surface. Fresh water is on one slide of the gate.
A. Evaluate the total hydrostatics force on the gate in kN.
B. Locate the point of action of the total hydrostatic force from the vertex on the
plane of the gate in m.
C. If the gate is hinged at the bottom, evaluate the force normal to the gate at its
