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
It is clear from the two graphs, the ultimate tensile strength for material (ii) is greater, hence material (ii) is elastic over larger region as compared to material (i).
For material (ii) fracture point is nearer, hence it is more brittle.

The stress and strain graphs for two materials, A and B are shown here. Answer the following: give reasons

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. The stress strain graph for two materials A and B is shown in the following figure: The time in which the two materials regain their original status is t_(A) and t_(B) related as t_(B)=2t_(B) . Then the material under elastic aftereffect (relatively) is
