The stress and strain graphs for two mat...

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

A

Which material has greater Young's modulus?

B

Which material is more ductile?

C

Which material is more brittle?

D

Which material has greater tensile strength?

Text Solution

Verified by Experts

a. A because the Young's modulus is given by the slope of the stress strain plot. The slope is greater for a.
b. `A` because ductility is givne by the extent of plastic deformation. This is greater for a
c. `B` because for a brittle material the plastic region is small.
d. `A` because stress required for fracture is greater for a.

The stress- strain graphs for materials A and B are as shown. Choose the correct alternative

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: If the intensity of A and B is E_(A) and E_(B) , respectively

The stress-strain graphs for two materials A and B are shown in the figure. The graphs are drawn to the same scale. (a) Which material has a greater Young's modulus ? (b) Which material is more ductile ? (c) Which material is more brittle? (d) Which of the two is the stronger material ?

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
