1.) Situation 11. A rectangular vertical gate, 0.60 m wide and 2.45 m high and weighing 1.78 kN, is hinged at the bottom. There is water on both sides of the gate, 4.9 m on one side and 1.80 m on the other. The gate, however, is held in place by a horizontal force F applied at the top of the gate. Under the above conditions, determine the horizontal force F and the amount and direction of the reaction at the hinge. Assume weight of water to be 9.81 kN/cu.m.
