An engineer proposes as a solution to the problem of the dam, to reinforce it according to the figure shown, but now the critical height h of the water level must be determined, which would make the indicated concrete reinforcement on the verge of overturning due to the water pressure. The density of the concrete 2.40 Mg/m^3, H=18m and d= 6m. Hints: use typical values of water, consider one meter width of the dam to then generalize and don't forget point A.
2. A dam consists of continuous flat-plat barriers whose masses are negligible. Supporting struts A, B, C and D are placed every 3 metres along the dam structure.

5. A dam is triangular in cross-section with the upstream face vertical. Water is flushed with the top. The dam is 8m high and 6m wide at the base and weighs 2.4 tons per cubic meter. The coefficient of friction between the base and the foundation is 0.8. Determine (a) maximum and minimum unit pressure on the foundation, and (b) factors of safety against overturning and against sliding. (* 6.

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.
