A beam has dimensions of b = 16 in., h = 26 in., and d = 23.5 in. and is reinforced with 3 No. 5 bars. The concrete strength is 10,000 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the compressive stress block is a = 0.410294 in. and the strain in the reinforcement is εs = 0.108688, determine the strength φMn for this beam. Assume the transverse reinforcement is not spirals.

A simply supported beam with dimensions of b = 12 in., h = 24 in., d = 21.5 in., and L = 21 ft supports a uniform service (unfactored) dead load consisting of its own weight plus 1.3 kips/ft and a uniform service (unfactored) live load of 1.1 kips/ft. The concrete is normal-weight concrete. Determine the moment due to the factored loads, Mu.
