Question 1
What is the primary purpose of a soil compaction test in civil
engineering?
A. To determine soil color
B. To measure soil temperature
C. To increase soil density and improve strength
D. To identify soil microorganisms
Rationale: Soil compaction tests are used to improve the engineering
properties of soil by reducing air voids, increasing density, and
enhancing load-bearing capacity, which is essential for foundations
and pavement structures.
Question 2
,Which law governs the relationship between stress and strain in the
elastic region of a material?
A. Newton’s Law
B. Bernoulli’s Principle
C. Hooke’s Law
D. Darcy’s Law
Rationale: Hooke’s Law states that stress is directly proportional to
strain within the elastic limit of a material, forming the basis of elastic
deformation analysis in structural engineering.
Question 3
What is the standard unit of force in the International System of Units
(SI)?
A. Joule
B. Watt
C. Pascal
D. Newton
Rationale: The Newton is the SI unit of force, defined as the force
required to accelerate a 1 kg mass at 1 m/s².
,Question 4
Which material is most commonly used in reinforced concrete for
tensile strength?
A. Timber
B. Aluminum
C. Brick
D. Steel
Rationale: Steel reinforcement is used in concrete because it has high
tensile strength, complementing concrete’s high compressive strength.
Question 5
What is the main purpose of a retaining wall?
A. To support roofs
B. To carry vertical loads only
C. To resist lateral earth pressure
D. To improve drainage only
Rationale: Retaining walls are designed to hold back soil or other
materials and resist lateral pressure from earth or water.
, Question 6
Which test is used to determine the workability of concrete?
A. Proctor test
B. CBR test
C. Slump test
D. Atterberg limits test
Rationale: The slump test measures the consistency and workability of
fresh concrete by observing how much it settles after the cone is
removed.
Question 7
What is the main function of a beam in structural systems?
A. To resist torsion only
B. To carry axial loads
C. To resist bending loads
D. To store energy
Rationale: Beams primarily resist bending caused by loads applied
perpendicular to their longitudinal axis.
