A beam has dimensions of b = 16 in., h = 22 in., and d = 19.5 in. and is reinforced with 4 No. 7 bars. The concrete strength is 9,100 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the nominal moment capacity, Mn, of the beam.

Write the sum using summation notation, assuming the suggested pattern continues. 4 – 24 + 144 – 864 + … (7 points)
