The stress-strain graphs for two materi...

The stress-strain graphs for two materials are shown in Fig. 7(EP).3 (assume 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).

Text Solution

Verified by Experts

The correct Answer is:
C, D
From graphs it is clear that ultimate strength of material (ii) is greater than that of material (i). Therefore, the elatic behaviour of material (ii) is over a largeer region of strain as compared to matterial (i). If the fracture point of a matterial is closer to ultimate strength point, then the material is a brittle material. Therefore, the material (ii) is more brittle than material (i).

Materials get deformed when force is applied. Some of them regain their status when the applied force is removed. They are termed as elastic. Those of which not regaining are called plastic. There may be delay in the regaining in some materials. They are said to have got elastic aftereffect, since they have gone beyond the elastic limit. Repeated application and removal of force leads to fatigueness in the material. Fatigued materials may break at any point time and so are avoided.
