A beam has dimensions of b = 18 in., h = 28 in., and d = 25.5 in. and is reinforced with 2 No. 7 bars. The concrete strength is 4,000 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the nominal moment capacity, Mn, of the beam.

A beam has dimensions of b = 16 in., h = 26 in., and d = 23.5 in. and is reinforced with 2 No. 7 bars. The concrete strength is 4,900 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth to the neutral surface is c = 1.342152 in., determine the strain in the reinforcement.

A beam has dimensions of b = 18 in., h = 26 in., and d = 23.5 in. and is reinforced with 3 No. 8 bars. The concrete strength is 5,500 psi, and the yield strength of the reinforcement is 60,000 psi. Assuming the reinforcement has yielded, determine the depth to the neutral axis, c.
