A triangular dam has a vertical upstream face 30 m high from the horizontal base. The depth of water is 27 m on the vertical face, the concrete weighs 23.5 kN/m³. a. Determine the minimum width of the base such that the resultant force falls within the middle thirds, neglecting hydrostatic uplift. b. Minimum coefficient of friction to prevent sliding. c. Determine the shearing stress (simple) at the depth of 10 m above the horizontal base.
