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 3,100 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the strength Mn for this beam.

A classmate has suggested a beam design that has dimensions of b = 16 in., h = 28 in., and d = 25.5 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?

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. For the results given below, determine the strength Mn for this beam.a = 3.809 in. (depth of concrete stress block)Cc = 165.8 kips (compressive force in concrete)Cs = 23.8 kips (compressive force in steel)T = 189.6 kips (tensile force in steel)

Charles has a headache. He opens the medicine cabinet, takes out some medicine, and swallows a couple of pills, then closes the cabinet door. Later, his headache begins to subside. What is the consequence for swallowing the pills?

A classmate has suggested a beam design that has dimensions of b = 12 in., h = 28 in., and d = 25.5 in. and is reinforced with 4 No. 11 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?

Emilia sees a car approaching, and she stops walking. Emilia hands a valet her ticket and then her car approaches. Emilia sees a car approaching, and she waves. The approaching cars in each scenario are examples of:

A beam is singly reinforced with the reinforcement in two rows. The bottom row contains 8 No. 6 bars at a depth of 24 in. The top row contains 6 No. 8 bars at a depth of 18 in. Determine the effective (centroidal) depth, d, of the steel.

A beam has dimensions of b = 20 in., h = 10 in., and d = 7.5 in. and is reinforced with 5 No. 5 bars. The concrete strength is 4,400 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 1.498 in., does the reinforcement yield?

Ralph is the behaver. Which of the following is an example of an antecedent?

A beam has dimensions of b = 20 in., h = 12 in., and d = 9.5 in. and is reinforced with 5 No. 6 bars. The concrete strength is 2,900 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 3.15 in., does the reinforcement yield?
