1. What is the primary purpose of a structural load analysis?
A) To determine material cost
B) To ensure stability and safety of the structure
C) To calculate labor requirements
D) To design the aesthetic features of the structure
Answer: B
Rationale: Structural load analysis ensures that the structure can safely
withstand applied loads without failure.
2. Which type of stress occurs when a material is subjected to
twisting?
A) Tensile stress
B) Compressive stress
C) Shear stress
D) Torsional stress
Answer: D
Rationale: Torsional stress is caused by twisting forces acting on a
material.
,3. In fluid mechanics, Bernoulli’s equation is used to describe:
A) Conservation of mass
B) Conservation of energy along a streamline
C) Conservation of momentum
D) Turbulence effects
Answer: B
Rationale: Bernoulli’s equation relates pressure, velocity, and elevation
along a streamline, representing energy conservation in fluid flow.
4. What is the main advantage of a truss structure over a beam?
A) Easier to paint
B) Efficient in carrying axial loads
C) Requires no maintenance
D) Resists torsion better
Answer: B
Rationale: Trusses are designed to efficiently carry axial loads through
members in tension and compression.
5. The modulus of elasticity (E) represents:
A) A material’s ability to resist permanent deformation
B) A material’s density
C) A material’s yield strength
D) A material’s ability to return to its original shape after stress
,Answer: D
Rationale: Modulus of elasticity quantifies how much a material
deforms elastically under stress.
6. What is the primary function of a foundation?
A) Reduce building cost
B) Provide support and transfer loads to soil
C) Control building temperature
D) Enhance architectural appearance
Answer: B
Rationale: Foundations distribute structural loads safely to the soil to
prevent settlement or failure.
7. In electrical engineering, Ohm’s Law is expressed as:
A) V = I × R
B) V = I / R
C) P = I × V
D) R = V / P
Answer: A
Rationale: Ohm’s Law relates voltage (V), current (I), and resistance (R)
in an electrical circuit.
8. Which type of soil is most prone to settlement under load?
A) Sand
B) Gravel
, C) Clay
D) Rock
Answer: C
Rationale: Clay is compressible and tends to consolidate over time
under load, causing settlement.
9. What is the primary purpose of a surge tank in water distribution?
A) Increase water velocity
B) Reduce water hammer and pressure fluctuations
C) Filter water
D) Heat water
Answer: B
Rationale: Surge tanks absorb sudden changes in water flow to prevent
pressure surges.
10. In HVAC design, what does the term “CFM” stand for?
A) Cubic feet per minute
B) Centrifugal fan measurement
C) Cooling flow measurement
D) Compressed fluid metric
Answer: A
Rationale: CFM quantifies the volume of air moved per minute, critical
in HVAC sizing.
11. A cantilever beam is:
