A simply supported beam with dimensions of b = 12 in., h = 26 in., d = 23.5 in., and L = 20 ft supports a uniform service (unfactored) dead load consisting of its own weight plus 1.7 kips/ft and a uniform service (unfactored) live load of 1.0 kips/ft. The concrete is normal-weight concrete. Determine the moment due to the factored loads, Mu.
