One of the primary reasons for using compressive reinforcement will be to increase the ______ of a given beam section.

A beam has dimensions of b = 18 in., h = 22 in., and d = 19.5 in. and is reinforced with 3 No. 6 bars. The concrete strength is 3,400 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 = 30 in., and d = 27.5 in. and is reinforced with 4 No. 5 bars. The concrete strength is 10,000 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 = 22 in., and d = 19.5 in. and is reinforced with 3 No. 5 bars. The concrete strength is 4,600 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the compressive stress block is a = 0.891944 in. and the strain in the reinforcement is εs = 0.050781, determine the strength φMn for this beam. Assume the transverse reinforcement is not spirals.

Since your first birthday, your grandparents have been depositing $1,200 into a savings account on every one of your birthdays. The account pays 6% interest annually. Immediately after your grandparents make the deposit on your 18th birthday, the amount of money in your savings account will be closest to ________.

16. 11C-methionine MET crosses intact blood brain barriers.

A simply supported beam with dimensions of b = 10 in., h = 24 in., d = 21.5 in., and L = 20 ft supports a uniform service (unfactored) dead load consisting of its own weight plus 1.2 kips/ft and a uniform service (unfactored) live load of 1.0 kips/ft. The concrete is normal-weight concrete. Determine the moment due to the factored loads, Mu.      

Which symbol represents the effective width of the compression zone for a flanged section with compression in the flange?

A classmate has suggested a beam design that has dimensions of b = 12 in., h = 30 in., and d = 27.5 in. and is reinforced with 4 No. 14 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?

Adjacent span loading is the common loading pattern for determining maximum negative moments at supports due to live load.
