Determine the resultant hydrostatic force F on the triangular gate, which is hinged at the bottom edge and held by the reaction R T at the upper corner. Express F in terms of , h and W. Also determine the ratio R T /F. Neglect the weight of the gate. 5. Determine the minimum volume of concrete ( concrete = 23.6 kN/m 3 ) needed to keep the gate (1-m wide) in a closed position, l = 2m.
