A beam has dimensions of b = 16 in., h = 30 in., and d = 27.5 in. and is reinforced with 4 No. 6 bars. The concrete strength is 2,500 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.

Hydrogen gas and nitrogen gas combine to form NH3. If there are 16.0 grams of hydrogen gas available, what is the mass of nitrogen gas needed for the reaction to go to completion?

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 2,800 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.

In design, the objective is to select a suitable cross section, dimensions, concrete strength, etc. given a specific factored design moment. There are many possible solutions.

A beam has dimensions of b = 14 in., h = 28 in., and d = 25.5 in. and is reinforced with 2 No. 8 bars. The concrete strength is 5,200 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth to the neutral surface is c = 1.939237 in., determine the strain in the reinforcement.

Which symbol represents the cross-sectional area of the reinforcement near the tension face of a reinforced concrete beam?

One of the primary reasons for using compressive reinforcement will be to increase the ______ of a given beam section.

A beam has dimensions of b = 18 in., h = 22 in., and d = 19.5 in. and is reinforced with 3 No. 6 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 depth to the neutral axis, c.

A beam has dimensions of b = 14 in., h = 30 in., and d = 27.5 in. and is reinforced with 4 No. 5 bars. The concrete strength is 10,000 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.

A beam has dimensions of b = 16 in., h = 22 in., and d = 19.5 in. and is reinforced with 3 No. 5 bars. The concrete strength is 4,600 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the compressive stress block is a = 0.891944 in. and the strain in the reinforcement is εs = 0.050781, determine the strength φMn for this beam. Assume the transverse reinforcement is not spirals.
