You are considering a beam design that has dimensions of b = 16 in., h = 30 in., and d = 27.5 in. The beam is singly reinforced with all of the reinforcement in a single row. The concrete strength is 8,200 psi, and the yield strength of the reinforcement is 60,000 psi. What cross-sectional area of reinforcement is needed to achieve a strain in the reinforcement of 0.0075?

A beam has dimensions of b = 14 in., h = 30 in., d’ = 2.5 in., and d = 27.5 in. It is reinforced with 2 No. 5 bars on the compression side and 5 No. 8 bars on the tension side. The concrete strength is 2,500 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 7.961 in., determine the force in the compression reinforcement, Cs.
