A beam is singly reinforced with the reinforcement in two rows. The bottom row contains 6 No. 7 bars at a depth of 14 in. The top row contains 3 No. 6 bars at a depth of 9.5 in. Determine the effective (centroidal) depth, d, of the steel.

[U2Q] A calculator was placed on a table in front of Faris. This is an example of a:

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.

Gear A has a diameter of 1.34 in., and gear B has a diameter of 1.72 in. If the pointer needs to be rotated 52° CW, how much should the motor be rotated?

A force of P = 22 N is applied to a lever at the end of a composite shaft. Sleeve (1) has a polar moment of inertia of 98,600 mm4 and a shear modulus of 1.5 GPa. Core (2) has a polar moment of inertia of 32,600 mm4 and a shear modulus of 0.7 GPa. Determine the torque produced in sleeve (1). Let a = b = 230 mm.

Gear A has a diameter of 1.48 in., and gear B has a diameter of 2.00 in. If the pointer needs to be rotated 57° CW, how much should the motor be rotated?

A beam has dimensions of b = 18 in., h = 26 in., and d = 23.5 in. and is reinforced with 5 No. 6 bars. The concrete strength is 5,200 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the strength Mn for this beam.

A torque of TC = 670 N·m is applied to the aluminum [G = 68 GPa] shaft. Segment (1) has a diameter of 69 mm, and segment (2) has a diameter of 37 mm. Determine the angle of twist at C. Let L1 = 0.53 m and L2 = 0.40 m.

A beam has dimensions of b = 16 in., h = 24 in., and d = 21.5 in. and is reinforced with 2 No. 8 bars. The concrete strength is 5,500 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the strength Mn for this beam.
