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?

Gear A has 69 teeth, and gear B has 55 teeth. If a torque of 66 lb·in. and a speed of 570 rpm is required at C, determine the minimum power that the motor must provide.

A beam has dimensions of b = 20 in., h = 10 in., and d = 7.5 in. and is reinforced with 5 No. 6 bars. The concrete strength is 4,100 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 2.241 in., does the reinforcement yield?

A beam has dimensions of b = 20 in., h = 10 in., and d = 7.5 in. and is reinforced with 4 No. 8 bars. The concrete strength is 5,300 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 2.681 in., does the reinforcement yield?
