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 (1m wide) in a closed position, l = 2m. Note the hinge at the bottom of the gate. air at P atm air at P atm hinge l W hinge View AA water A A h h F water R T l Submerged concrete block hinge water stop gate g r g r air at P atm...
