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.

A two-month old boy presents for his well child exam, but mom’s primary concern is his crying and fussiness throughout the day, especially in the evenings. His mother is convinced it is his milk-based formula (Similac Advance) which he has been on for the past 3 weeks as he has weaned off breast milk. Everything else on history & a complete exam is within normal limits. Answer the next two (2) questions based on this case. You decide to trial a different formula to see if formula is the problem. Your best recommendation to accomplish this is:

Delayed due to several respiratory illnesses, an 11-month old boy was seen for a well visit (his last well visit was at 4 months). At 11 months, Kenny should receive appropriate 6 months immunizations including DTaP #3, IPV #3, PCV-13 #3, & Hep B; he was then caught up with his vaccinations. Kenny is now 15 months of age and is in clinic for a check-up and vaccines again. He has a mild cold today with a temperature of 99.2 axillary. What vaccines should be given today:

A beam has dimensions of b = 18 in., h = 28 in., and d = 25.5 in. and is reinforced with 2 No. 5 bars. The concrete strength is 5,500 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the compressive stress block is a = 0.442068 in. and the strain in the reinforcement is εs = 0.131114, determine the strength φMn for this beam. Assume the transverse reinforcement is not spirals.

A beam has dimensions of b = 14 in., h = 30 in., d’ = 2.5 in., and d = 27.5 in. It is reinforced with 2 No. 5 bars on the compression side and 4 No. 8 bars on the tension side. The concrete strength is 3,700 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 4.481 in., determine the force in the compression reinforcement, Cs.
