6. Water backs up behind a concrete dam as shown in figure. Leakage under the foundation gives a pressure distribution under the dam as indicated. If the water depth, h, is too great, the dam will topple over about its toe (point A). For the dimensions given, determine the facto of safety against overturning moment if L= 120 ft and h 50 ft. Base your analysis on a unit length of the dam. The specific weight of concrete is 150 Ib/ft³. 80ft Water h Water h - 10 A= yh
