Match the properties in Column I with the options in Column II
| Column I | Column II |
|---|---|
| P. Toughness | 1. Resistance to plastic deformation |
| Q. Resilience | 2. Time dependent permanent deformation under constant load |
| R. Creep | 3. Total elongation at failure |
| S. Hardness | 4. Area under the stress-strain curve |
| 5. Area under the elastic part of the stress-strain curve |
Answer: C
The match is P-4, Q-5, R-2, S-1.
- Toughness is the energy absorbed up to fracture, the whole area under the stress-strain curve.
- Resilience is the energy stored elastically, the area under the elastic part of the curve.
- Creep is time-dependent permanent deformation under constant load, usually at high temperature.
- Hardness is resistance to plastic deformation, typically local indentation.
'Total elongation at failure' is ductility, which is not in Column I, so options that use item 3 are wrong. Swapping toughness and resilience, as two of the options do, confuses the whole curve with its elastic part.
