1. In structural engineering, the relationship between stress and strain in the
elastic range of a material is defined by which law?
A. Newton’s Law
B. Hooke’s Law
C. Pascal’s Law
D. Bernoulli’s Law
Correct Answer: Hooke’s Law
Hooke’s Law states that stress is directly proportional to strain within the elastic
limit of a material, expressed as σ = Eε where E is the modulus of elasticity.
2. Which type of load represents the permanent weight of structural elements
such as beams, columns, and slabs?
,A. Live load
B. Impact load
C. Dead load
D. Wind load
Correct Answer: Dead load
Dead loads are constant loads that remain unchanged over time and include the
weight of structural components and fixed installations.
3. The point where the resultant of a distributed load acts is called the:
A. Neutral axis
B. Centroid
C. Shear center
D. Plastic hinge
Correct Answer: Centroid
For distributed loads, the resultant force acts at the centroid of the load
distribution.
4. Which structural member primarily resists compressive forces?
A. Beam
B. Column
C. Tie
D. Cable
Correct Answer: Column
Columns are vertical members designed primarily to carry compressive loads from
beams, slabs, or other structural components.
5. The unit of stress in the SI system is:
A. Newton
B. Joule
C. Pascal
D. Watt
, Correct Answer: Pascal
Stress is defined as force per unit area, measured in Pascals (N/m²).
6. A simply supported beam has maximum bending moment at:
A. Support
B. Quarter span
C. Midspan
D. Zero location
Correct Answer: Midspan
For a uniformly distributed load on a simply supported beam, the maximum
bending moment occurs at the midpoint.
7. The neutral axis in a bending member is the location where:
A. Maximum compression occurs
B. Maximum tension occurs
C. Stress equals zero
D. Shear equals zero
Correct Answer: Stress equals zero
The neutral axis separates the tension and compression zones where bending
stress is zero.
8. The slenderness ratio of a column is defined as:
A. Length divided by width
B. Effective length divided by radius of gyration
C. Area divided by length
D. Load divided by area
Correct Answer: Effective length divided by radius of gyration
The slenderness ratio determines the likelihood of buckling in compression
members.
9. Which type of structural load varies depending on building occupancy?
