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:
Answer: 48 ksi
AISC Table J3.2 lists Fnv = 48 ksi for A325 bolts in bearing-type connections.
The primary purpose of a geotextile filter in a drainage system is to:
Answer: Allow water to pass while retaining soil particles
Geotextile filters are designed to be permeable to water yet retain fine soil particles to prevent piping.
In the context of the PE exam depth modules, the Civil PE exam is structured with a breadth section followed by:
Answer: A depth section in one of five specialties
The PE Civil exam consists of a morning breadth section and an afternoon depth section in one specialty.
Darcy's Law states that the flow rate through a porous medium is proportional to:
Answer: Hydraulic gradient and cross-sectional area
Q = kiA, where k = hydraulic conductivity, i = hydraulic gradient, A = cross-sectional area.
A traffic engineer observes 300 vehicles passing a point in 5 minutes. The flow rate in vehicles per hour is:
Answer: 3,600 vph
Flow = (300 vehicles / 5 min) × 60 min/hr = 3,600 vph.
For a reinforced concrete beam, the ACI 318 minimum concrete cover requirement for main reinforcement in a beam not exposed to weather is:
Answer: 1.5 in
ACI 318 Table 20.6.1.3 requires 1.5 in of cover for beams and columns not exposed to weather.
The consolidation settlement of a clay layer depends primarily on which soil parameter?
Answer: Compression index (Cc) and initial void ratio (e0)
Primary consolidation settlement uses Sc = [Cc/(1+e0)] × H × log(σ'f/σ'0).
