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

A 84-lb child and a 23-lb cardboard box are on an oak beam. Determine the vertical reaction force at the left end of the beam. Let a = 23 in., b = 34 in., and c = 49 in.

A force of P = 24 N is applied to a lever at the end of a composite shaft. Sleeve (1) has a polar moment of inertia of 79,900 mm4 and a shear modulus of 1.1 GPa. Core (2) has a polar moment of inertia of 23,000 mm4 and a shear modulus of 0.6 GPa. Determine the torque produced in sleeve (1). Let a = b = 230 mm.

A torque of TC = 970 N·m is applied to the aluminum [G = 74 GPa] shaft. Segment (1) has a diameter of 89 mm, and segment (2) has a diameter of 41 mm. Determine the angle of twist at C. Let L1 = 0.55 m and L2 = 0.37 m.

You are considering a beam design that has dimensions of b = 16 in., h = 22 in., and d = 19.5 in. The beam is singly reinforced with all of the reinforcement in a single row. The concrete strength is 7,000 psi, and the yield strength of the reinforcement is 60,000 psi. What cross-sectional area of reinforcement is needed to achieve a strain in the reinforcement of 0.0075?

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 3,100 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 5.205 in., determine the force in the compression reinforcement, Cs.

You are considering a beam design that has dimensions of b = 18 in., h = 28 in., and d = 25.5 in. The beam is singly reinforced with all of the reinforcement in a single row. The concrete strength is 8,200 psi, and the yield strength of the reinforcement is 60,000 psi. What cross-sectional area of reinforcement is needed to achieve a strain in the reinforcement of 0.0075?

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?

Gear A has a diameter of 1.02 in., and gear B has a diameter of 1.37 in. If the pointer needs to be rotated 48° CW, how much should the motor be rotated?
