Elastic Modulie

Question

The stress-strain curves are drawn for two different materials X and Y. It is observed that the ultimate strength point and the fracture point are close to each other for material X but are far apart for material Y. We can say that materials X and Y are likely to be (respectively),

Moderate

A

Plastic and ductile
B

Ductile and brittle
C

Brittle and ductile
D

Brittle and plastic

Solution

As given that fracture point and ultimate strength point is close for material X, hence X is brittle in nature and both points are far apart for material Y hence it is ductile. i.e X is brittle and Y is ductile in nature.
