Describe the transformations of the graph of y = 2f(-x) + 5.

A beam has dimensions of b = 18 in., h = 10 in., and d = 7.5 in. and is reinforced with 4 No. 7 bars. The concrete strength is 3,800 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 2.914 in., does the reinforcement yield?

(08.04 LC) Which type of substance ionizes partially and gives off hydrogen ions when dissolved in water?

A beam has dimensions of b = 14 in., h = 24 in., and d = 21.5 in. and is reinforced with 2 No. 5 bars. The concrete strength is 4,300 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 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 4 No. 7 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?
