As represents the cross sectional area of reinforcement on the tension side of the beam, and A’S represents the cross sectional area of reinforcement on the compression side of the beam.

The compressive and tensile forces act through the centroid of their respective stress blocks.

If C represents the internal compressive force and T represents the internal tensile force in a singly-reinforced concrete beam that has no applied axial load, then _______.

Give the chemical formulas for the following compounds:                                                       manganese(IV) carbonate Potassium phosphate Magnesium hydroxide Calcium nitrite

12. When performing a CT of the sinus cavities, a technologist would choose an acquisition protocol that emphasizes ___________ resolution then reconstruct the images with a specialized ________.   

A beam has dimensions of b = 16 in., h = 26 in., and d = 23.5 in. and is reinforced with 3 No. 5 bars. The concrete strength is 10,000 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the compressive stress block is a = 0.410294 in. and the strain in the reinforcement is εs = 0.108688, determine the strength φMn for this beam. Assume the transverse reinforcement is not spirals.

LISTENING COMPREHENSION (4 pts) The Travel Blog (Vocabulary: Travel and the Environment) José is a travel blogger. Listen to José describing things that he has seen and done while traveling. Listen to what he says and then select the corresponding statement.

A beam has dimensions of b = 18 in., h = 28 in., and d = 25.5 in. and is reinforced with 5 No. 6 bars. The concrete strength is 7,600 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.
