Question

Information P Flag question Use the stress-strain diagram below to answer questions 10-12. A B a E

Answer 1

Question 10

Material A is more brittle. Because brittle materials fracture at much lower strain values. It fail suddenly.

So option a. A IS correct.

Question 11

Material A is more stronger. Even though brittle material absorb relatively very less energy prior to failure but brittle material have high strength. So more the material is brittle, larger will be its strength.

So option a. A IS correct.

Question 12

Material is having more toghness. Material B absorb more energy before fracture. Toughness is the area of stress strain diagram up to fracture point. It is the ability of material to absorb energy and prastically deform without fracturing.

So option b. B IS correct.
