Advantages of technology include all of the following except:

Which of the following is not one of the ethical issues associated with Pricing (specifically Domestic Pricing) we discussed in class.

A 119-mm-long beam supports a load of P = 41 N at midspan. The cross section is rectangular with width b = 27 mm and height h = 50 mm. Determine the magnitude of the horizontal shear stress at the centroid of the cross section.

Which of the following groups in the molecule shown below is most likely to participate in an electrostatic interaction involving dipoles?        

A 115-mm-long beam supports a load of P = 33 N at midspan. The cross section is rectangular with width b = 28 mm and height h = 45 mm. Determine the magnitude of the horizontal shear stress at the centroid of the cross section.

A continuous beam’s flexural reinforcement must extend at least _____ from the point where it is no longer needed to resist tension. Assume f’c = 4,000 psi, fyt = 40,000 psi, b1 = 32 in., b2 = 16 in., d1 = 4 in., d2 = 15 in., and that there are three No. 6 longitudinal tension bars and No. 3 stirrups at 10 in. o.c. The stirrup hooks are 90°.

A simply-supported beam has a 3 kip/ft uniformly-distributed load over the entire 10-ft span. What is the magnitude of the maximum shear force in the beam?

If φVc = 14 kip and Vu = 27 kip, are stirrups required?

Compute φVn for the cross section shown. Assume f’c = 8,000 psi, fyt = 40,000 psi, b = 13 in., d = 20 in., and that there are four No. 9 longitudinal tension bars and No. 5 stirrups at 9 in. o.c.

Compute φVn for the cross section shown. Assume f’c = 4,500 psi, fyt = 40,000 psi, d = 30 in., w = 24.5 in., t = 4 in., and that there are four No. 7 longitudinal tension bars and No. 4 stirrups at 11 in. o.c.
