A 123-mm-long beam supports a load of P = 40 N at midspan. The cross section is rectangular with width b = 29 mm and height h = 60 mm. Determine the magnitude of the horizontal shear stress at the centroid of the cross section.

A beam has dimensions of b = 16 in., h = 24 in., and d = 21.5 in. and is reinforced with 2 No. 6 bars. The concrete strength is 9,100 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the strength Mn for this beam.

Which is (are) NOT found in the wall of the large intestine?

Compute φVn for the cross section shown. Assume f’c = 3,000 psi, fyt = 40,000 psi, d = 24 in., w = 18.5 in., t = 4 in., and that there are four No. 9 longitudinal tension bars and No. 4 stirrups at 8 in. o.c.

Stirrups are unable to resist shear unless they are crossed by an inclined crack.

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 2,800 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 = 4.828 in. (depth of concrete stress block)Cc = 159.4 kips (compressive force in concrete)Cs = 30.2 kips (compressive force in steel)T = 189.6 kips (tensile force in steel)

Medications to treat generalized anxiety disorder (GAD) can include a selective serotonin reuptake inhibitor (SSRI), and/or serotonin and norepinephrine reuptake inhibitor (SNRI).These medications are advantageous due to the following affects:

Which of these blood pressure readings is considered to be Stage 2 hypertension per the American Heart Association guidelines?

When faced with severe architectural restrictions on the dimensions of a beam, a designer may be forced to use a doubly reinforced section.

A beam has dimensions of b = 14 in., h = 26 in., and d = 23.5 in. and is reinforced with 3 No. 5 bars. The concrete strength is 4,000 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the strength Mn for this beam.
