A beаm hаs dimensiоns оf b = 16 in., h = 26 in., аnd d = 23.5 in. and is reinfоrced 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.
