1. What is the primary purpose of materials testing in engineering?
A. To increase production speed
B. To determine material properties and suitability for use
C. To reduce manufacturing costs
D. To decorate materials
Rationale: Materials testing ensures materials meet required strength,
durability, and performance standards for safe application.
2. Which test measures a material’s resistance to being pulled apart?
A. Compression test
B. Hardness test
C. Impact test
D. Tensile test
Rationale: Tensile testing evaluates how much pulling force a material
can withstand before failure.
3. Which instrument is commonly used to measure hardness?
,A. Micrometer
B. Vernier caliper
C. Rockwell hardness tester
D. Spectrometer
Rationale: The Rockwell tester measures indentation resistance to
determine hardness.
4. What does ductility describe?
A. Resistance to corrosion
B. Ability to deform under tensile stress without breaking
C. Electrical conductivity
D. Thermal expansion
Rationale: Ductility indicates how much a material can stretch before
fracture.
5. Which test evaluates material behavior under sudden force?
A. Tensile test
B. Fatigue test
C. Impact test
D. Compression test
Rationale: Impact tests measure toughness under sudden loading
conditions.
6. The SI unit of stress is:
,A. Newton
B. Joule
C. Pascal
D. Pascal (N/m²)
Rationale: Stress is force per unit area measured in Pascals.
7. Strain is defined as:
A. Force applied
B. Change in pressure
C. Change in length divided by original length
D. Weight of material
Rationale: Strain measures deformation relative to original dimensions.
8. Which property describes resistance to scratching?
A. Toughness
B. Ductility
C. Hardness
D. Elasticity
Rationale: Hardness indicates resistance to surface indentation or
scratching.
9. Which test is used to determine fatigue strength?
A. Tensile test
B. Cyclic loading test
, C. Compression test
D. Bend test
Rationale: Fatigue testing applies repeated loading cycles to simulate
service conditions.
10. What is elasticity?
A. Permanent deformation
B. Resistance to heat
C. Ability to return to original shape after deformation
D. Electrical resistance
Rationale: Elastic materials recover their original shape after stress
removal.
11. Which device measures dimensional accuracy?
A. Spectrometer
B. Caliper
C. Furnace
D. Tachometer
Rationale: Calipers measure internal, external, and depth dimensions.
12. What is brittleness?
A. Ability to stretch
B. Resistance to corrosion
