In a reinforced concrete beam, the neutral axis needs to be adjusted up and down until section equilibrium is established.

A beam has dimensions of b = 18 in., h = 12 in., and d = 9.5 in. and is reinforced with 4 No. 11 bars. The concrete strength is 4,700 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 6.388 in., does the reinforcement yield?

A 40-year-old female patient with a history of hypertension presents for a routine examination. Auscultation of the chest reveals a pansystolic murmur best heard at the cardiac apex, radiating to the axilla. There is a third heart sound, S3. The murmur is high pitched and harsh blowing. You listened to her heart using the diaphragm of the stethoscope when she was in the supine position. Which of the following is most likely the etiology of the murmur?

You are considering a beam design that has dimensions of b = 14 in., h = 22 in., and d = 19.5 in. The beam is singly reinforced with all of the reinforcement in a single row. The concrete strength is 4,300 psi, and the yield strength of the reinforcement is 60,000 psi. What cross-sectional area of reinforcement is needed to achieve a strain in the reinforcement of 0.0075?
