Concrete weights 23.5 kN/m^3 and water weights 9790 N/m^3. Coefficient of friction between the dam and foundation is 0.55. determine the factors of safety against sliding and against overturning, and also the soil pressure at the heel and toe. Assume hydrostatic uplift varies uniformly from full hydrostatic head at the heel of the dam to zero at the toe. consider 1m length of dam.
