Geotechnical and Hydraulic Engineering: Key Terms
and Principles for Civil Engineering
Questions And
Answers 2025 \2026
What is specific weight? - CORRECT ANSWER-The weight per unit
volume of a liquid at a standard temperature and pressure.
What is soil in Civil Engineering? - CORRECT ANSWER-Soil is found in the
Earth's crust and is an uncemented aggregate.
How does specific weight of liquid vary? - CORRECT ANSWER-Specific
weight of liquid does not remain constant at every place; it varies from
place to place on the earth.
What is negative skin friction on piles? - CORRECT ANSWER-Negative
skin friction on piles is caused by soft clay, decreases pile capacity, and
is due to relative settlement of soil.
What is metacentric height? - CORRECT ANSWER-Metacentric height is
the distance between the center of gravity of the floating body and the
metacenter.
, What happens when the metacenter is lower than the center of
gravity? - CORRECT ANSWER-The body will be in unstable equilibrium.
How is vertical stress intensity at depth due to a point load
characterized? - CORRECT ANSWER-It is directly proportional to the
depth.
What is the shear strength of cohesionless soil proportional to? -
CORRECT ANSWER-The shear strength of cohesionless soil is
proportional to the tangent of the angle of shearing resistance.
What is the porosity and void ratio when the volume of voids equals the
volume of solids? - CORRECT ANSWER-Porosity is 0.5 and void ratio is
1.0.
Where is the metacenter for stable equilibrium? - CORRECT ANSWER-
Above the center of gravity.
What do molecules of liquid get attracted to? - CORRECT ANSWER-
Molecules of liquid get attracted to adhesion.
What is the classification of soil greater than 75 mm in AASHTO? -
CORRECT ANSWER-It is classified as boulders.
