Question
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).

Solution
c and d
Explanation:
Because while we compare the ultimate tensile strength of materials we get that (ii) is greater than (i). Thus, (ii) is elastic as compared to (i) over the larger region which implies (ii) is elastic as compared to (i) over a larger region of strain.

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).
