A concrete dam retaining water is shown. If the specific weight of the concrete is 23.54 kN/m3, find the factor of safety against sliding. Assume there is a hydrostatic uplift that varies uniformly from full hydrostatic head at the heel of the dam to zero at the toe and that the coefficient of friction between dam and foundation soil is 0.45.
