One mole corresponds to 6.02 x 10-23 items

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. If the depth of the neutral axis is c = 4.481 in., determine the force in the compression reinforcement, Cs.

Determine β1 given that f’c = 7,000 psi.

You were instructed to begin the prewriting and outlining process for Paper 2. Below, please discuss the following: The topic you chose and why. What your tentative working thesis is.

Discuss your experiences with a tutor this week. What did you like? What did you dislike? Do you think you would take papers for other classes to the CLE in the future? Why or why not? Elaborate on your thoughts here.

The basic strength requirement from ACI 318 is “Reduced nominal strength ​≤ Factored load effects.”

A beam has dimensions of b = 14 in., h = 30 in., and d = 27.5 in. and is reinforced with 4 No. 6 bars. The concrete strength is 9,400 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth to the neutral surface is c = 1.452365 in., determine the strain in the reinforcement.

A beam has dimensions of b = 14 in., h = 26 in., d’ = 2.5 in., and d = 23.5 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)
