A beam is singly reinforced with the reinforcement in two rows. The bottom row contains 9 No. 7 bars at a depth of 24 in. The top row contains 5 No. 8 bars at a depth of 20 in. Determine the effective (centroidal) depth, d, of the steel.

Low-density lipoproteins (LDLs) are lipoproteins that 

Someone with a diet that is high in animal protein but low in vegetables is likely to have very active

A classmate has suggested a beam design that has dimensions of b = 16 in., h = 26 in., and d = 23.5 in. and is reinforced with 5 No. 8 bars. Assuming a cover of 1.5 in. and a stirrup diameter of 0.5 in., does the reinforcement fit within a single row as suggested?

Two-way slabs typically have flexural reinforcement in two principal horizontal directions.

You are examining a 66-year-old man with the diagnosis of heart failure. His symptoms include increased SOB, increased fatigue and a 10 pound weight gain over the past 7-10 days. Which of the following clinical symptoms is NOT typically found during the physical examination of a patient experiencing a heart failure exacerbation?

There are _______ deciduous teeth; these _______________.

Triiodothyronine is released by the ________________ and it results in  ________________.

A continuous beam’s flexural reinforcement must extend at least _____ from the point where it is no longer needed to resist tension. Assume f’c = 4,000 psi, fyt = 40,000 psi, d = 24 in., w = 16.5 in., and t = 5 in. There are five No. 6 longitudinal tension bars and No. 5 stirrups at 12 in. o.c.
