A concrete floor system with a ratio of the longer to the shorter span length that is less than or equal to 2 is usually considered a one-way system.

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.
