Question 1

Which mechanical property measures a material's ability to resist localized plastic deformation such as scratching or indentation?

Hardness Toughness Ductility Elasticity

Correct Answer:

Hardness

Question 2

What does Hooke's Law state for a material undergoing uniaxial tensile loading within its elastic limit?

Stress is directly proportional to strain Stress is inversely proportional to cross-sectional area squared Strain is proportional to total temperature change only Stress is proportional to the square of plastic elongation

Correct Answer:

Stress is directly proportional to strain

Question 3

In a standard tensile test specimen, how is normal stress (σ) calculated?

Applied axial force divided by initial cross-sectional area (F / A₀) Change in length divided by original length (ΔL / L₀) Original length divided by applied axial force (L₀ / F) Applied torque divided by polar moment of inertia (T / J)

Correct Answer:

Applied axial force divided by initial cross-sectional area (F / A₀)

Question 4

Which Charpy impact test result indicates a material with high impact toughness at room temperature?

High energy absorption with a fibrous, dull fracture surface Low energy absorption with a bright, crystalline fracture surface Zero energy absorption with complete intergranular cleavage Moderate energy absorption with rapid fatigue crack propagation

Correct Answer:

High energy absorption with a fibrous, dull fracture surface

Question 5

What is the primary objective of the quenching (temple) heat treatment applied to carbon steels?

To transform austenite rapidly into hard, brittle martensite To increase grain size and maximize electrical conductivity To induce complete recrystallization and minimize hardness To eliminate internal stresses while maintaining a purely ferritic microstructure

Correct Answer:

To transform austenite rapidly into hard, brittle martensite
