A 30-m high triangular dam has a vertical upstream face from the horizontal base. The depth of water on the upstream side of the dam is 27 m. If concrete weighs 23.5 kN/m³ and neglecting hydrostatic uplift, a. Determine the minimum width of the base such that the resultant force falls within the middle thirds. b. Determine the minimum coefficient of friction to prevent sliding.
