[U2Q] A fire alarm begins ringing. This is an example of a(n):

[U2Q] When Heidi dances like a chicken, sometimes people laugh about it, sometimes they shake their heads, and sometimes they tell her to stop. This is an example of a:

[U2Q] Ralph is the behaver. Which of the following is an example of an antecedent?

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 5 No. 8 bars on the tension side. The concrete strength is 2,800 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 7.179 in., determine the strain in the compression reinforcement, ε’s.

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 4,000 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 4.199 in., determine the strain in the compression reinforcement, ε’s.

[U2Q] After Elliot heard the garbage truck coming, he quickly walked to the kitchen to bring his garbage can out to the street. What effect did the antecedent have on behavior?  

[U2Q] Which of the following demonstrates an evocative effect on behavior? 

A classmate has suggested a beam design that has dimensions of b = 12 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?

Loads P = 33 N, Q = 86 N, and R = 21 N are applied to the structure. Determine the torque generated in segment (2). Let a = 117 mm, b = 77 mm, and c = 45 mm.

A torque of T = 340 lb·in. is applied to two pulleys and a copper-alloy shaft. Determine the minimum diameter of the shaft if its shear yield strength is 24 ksi.
