A simply supported beam with dimensions of b = 12 in., h = 24 in., d = 21.5 in., and L = 21 ft supports a uniform service (unfactored) dead load consisting of its own weight plus 1.7 kips/ft and a uniform service (unfactored) live load of 1.5 kips/ft. The concrete is normal-weight concrete. Determine the moment due to the factored loads, Mu.

A beam has dimensions of b = 16 in., h = 26 in., and d = 23.5 in. and is reinforced with 5 No. 7 bars. The concrete strength is 3,400 psi, and the yield strength of the reinforcement is 60,000 psi. Assuming the reinforcement has yielded, determine the tensile force T in the reinforcement.
