A trapezoidal masonry dam with a vertical upstream face is 6m. high, 0.60 m. at the top and 3 m. wide of the bottom. Wt. of concrete is 23.5 kN/m³. Location of hydrostatic force from the base of the dam is 1/3 of the depth of water. (a) Find the depth of water on the vertical upstream face if the value of x (x-bar) from the toe is 1.0 m (b) Using the computed depth of water, compute the hydrostatic uplift 'force if the uplift varies from full hydrostatic force ath the heel to zero at the toe. (c) Compute the factor of safety against sliding if the coefficient of firction on the base is equal to 0.80. Consider the hydrostatic uplift.
