Long answer type question.
Define stress and strain. What are their different types?
The stress-strain curves are drawn for two different materials X and Y. It is observed that the ultimate strength point and the fracture point are close to each other for material X but are far apart for material Y. We can say that materials X and Y are likely to be (respectively).
The stress-strain graphs for two materials are shown in figure (assume same scale).
 Material (i) |
 Material (i) |
- Material (ii) is more elastic than material (i) and hence material (ii) is more brittle.
- Material (i) and (ii) have the same elasticity and the same brittleness.
- Material (ii) is elastic over a larger region of strain as compared to (i).
- Material (ii) is more brittle than material (i).
