Question 1

A 1-inch diameter A325 bolt in single shear has a nominal shear strength. The AISC nominal shear stress for A325 bolts in a bearing-type connection is approximately:

Accepted Answer

48 ksi

Answer

AISC Table J3.2 lists Fnv = 48 ksi for A325 bolts in bearing-type connections.

Question 2

The primary purpose of a geotextile filter in a drainage system is to:

Accepted Answer

Allow water to pass while retaining soil particles

Answer

Geotextile filters are designed to be permeable to water yet retain fine soil particles to prevent piping.

Question 3

In the context of the PE exam depth modules, the Civil PE exam is structured with a breadth section followed by:

Accepted Answer

A depth section in one of five specialties

Answer

The PE Civil exam consists of a morning breadth section and an afternoon depth section in one specialty.

Question 4

Darcy's Law states that the flow rate through a porous medium is proportional to:

Accepted Answer

Hydraulic gradient and cross-sectional area

Answer

Q = kiA, where k = hydraulic conductivity, i = hydraulic gradient, A = cross-sectional area.

Question 5

A traffic engineer observes 300 vehicles passing a point in 5 minutes. The flow rate in vehicles per hour is:

Accepted Answer

3,600 vph

Answer

Flow = (300 vehicles / 5 min) × 60 min/hr = 3,600 vph.
