A concrete dam of trapezoidal cross-section with one face vertical has a thickness of 3.5 m. at the top and 15 m. at the bottom. It is 20 m. high and has a horizontal base. The inclined face is subjected to a water pressure, standing 18 m. above the base. The specific gravity of the concrete is 2.4. Assume no hydrostatic uplift. Determine: a. Total hydrostatic force acting perpendicular to the inclined surface b. Location of resultant force which intersects the base from the toe c. Pressure at heel and toe
