  • The stress-strain graphs for two materials are shown in Figure (assume same scale)

The stress-strain graphs for the two materials are shown in Figure (assume the same scale).

(a) Material (ii) is more elastic than material (i) and hence material (ii) is more brittle.
(b) Material (i) and (ii) have the same elasticity and the same brittleness.
(c) Material (ii) is elastic over a larger region of strain as compared to (i).
(d) Material (ii) is more brittle than material (i).

Answers (1)

The answer is the option (c) and (d)

If we compare the tensile strength, (ii) > (i)

So (ii) is more elastic as compared to (i) and hence option c is correct.

The fracture point for the material (ii) is closer than that of material (i). hence, (ii) is more brittle than (i), and option (d) is correct.
