A beаm hаs dimensiоns оf b = 14 in., h = 24 in., аnd d = 21.5 in. and is reinfоrced with 5 No. 7 bars. The concrete strength is 5,200 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the compressive stress block is a = 2.908856 in. and the strain in the reinforcement is εs = 0.014517, determine the strength φMn for this beam. Assume the transverse reinforcement is not spirals.
