dam a A masonry of trapezoidal cross-section, with one end face vertical, has thickness of 0.6 m at the top and 3 m at the bottom. It is 6.75 m high and the vertical face is subjected to water pressure, the water standing 4.6 m above the base at the upstream side. Assume that the hydrostatic uplift varies uniformly from 50% at the heel to zero at the toe. Use s = 2.4 for concrete. Compute the following: a. Vertical reaction of the foundation b. Distance of the vertical reaction from the toe. c. Factor of safety against overturning. d. Factor of safety against sliding. Use u = 0.6 e. Maximum pressure along the base due to the forces acting on the dam. f. Minimum pressure along the base due to the forces acting on the dam
