There is a dam shaped like a semicircle with 45° angulation. The dam consists of two structures: one 20 m high, generated by a second degree function, and the other rectilinear 10 m high. The forces on the dam should be analyzed in order to prevent its rupture. Determine: A) The graph of the resulting force as a function of the water height at the bottom of the dam B) The resulting force for a water height of 10 m C) The resulting force for a water height of 20 m 5,0 m 10,0 m 30,0 m 17,5 m

If a steel rectangular gate (see Figure 1) of 1.0m wide by 1.66 m high, is located in the wall of a reservoir. It is hinged at the top and acts as a relief valve such that when the water level reaches 1.35m above the top of the gate the gate starts to open allowing water to leave the reservoir. If the gate is inclined at 66º to the horizontal, and the density of steel is 7600 kg/m3, determine the thickness of the gate.
