A beam has dimensions of b = 18 in., h = 30 in., and d = 27.5 in. and is reinforced with 5 No. 6 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.

A beam has dimensions of b = 16 in., h = 24 in., and d = 21.5 in. and is reinforced with 5 No. 8 bars. The concrete strength is 6,700 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the nominal moment capacity, Mn, of the beam.

A client who works as a restaurant server and is 35 weeks gestation, telephones the labor and delivery unit after getting home from work and states, “I am feeling tightening in my abdomen about every 7-8 minutes.” Which of the following comments by the nurse is appropriate at this time?

After delivery of the fetal head, the physician struggles to deliver the rest of the fetal body. The nurse would anticipate which intervention to aid in the delivery of the fetal shoulders?

A beam has dimensions of b = 16 in., h = 28 in., and d = 25.5 in. and is reinforced with 5 No. 6 bars. The concrete strength is 3,700 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 = 26 in., and d = 23.5 in. and is reinforced with 5 No. 8 bars. The concrete strength is 9,700 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth to the neutral surface is c = 3.158758 in., determine the strain in the reinforcement.
