A simply supported beam with dimensions of b = 18 in., h = 26 in., d = 23.5 in., and L = 22 ft supports a uniform service (unfactored) dead load consisting of its own weight plus 1.2 kips/ft and a uniform service (unfactored) live load of 1.5 kips/ft. The concrete is normal-weight concrete. Determine the moment due to the factored loads, Mu.
