A beam has dimensions of b = 16 in., h = 24 in., and d = 21.5 in. and is reinforced with 2 No. 6 bars. The concrete strength is 7,000 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the compressive stress block is a = 0.554622 in. and the strain in the reinforcement is εs = 0.078407, determine the strength φMn for this beam. Assume the transverse reinforcement is not spirals.
