A simply supported beam with dimensions of b = 14 in., h = 22 in., d = 19.5 in., and L = 22 ft supports a uniform service (unfactored) dead load consisting of its own weight plus 1.8 kips/ft and a uniform service (unfactored) live load of 1.4 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 = 22 in., and d = 19.5 in. and is reinforced with 4 No. 5 bars. The concrete strength is 9,400 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth to the neutral surface is c = 0.89535 in., determine the strain in the reinforcement.

A beam has dimensions of b = 14 in., h = 26 in., and d = 23.5 in. and is reinforced with 5 No. 8 bars. The concrete strength is 8,500 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the strength Mn for this beam.

A beam has dimensions of b = 16 in., h = 30 in., and d = 27.5 in. and is reinforced with 4 No. 8 bars. The concrete strength is 7,600 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the compressive stress block is a = 1.834365 in. and the strain in the reinforcement is εs = 0.027133, determine the strength φMn for this beam. Assume the transverse reinforcement is not spirals.
