Question

the stress-strain curves are drawn for two different material x nd 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 that material X and Y are likely to be (respectively),

a)plastic and ductile
b)ductile and brittle
c) brittle and ductile
d) brittle and plastic​

Answer 1

Answer:

Material X is brittle but material Y is ductile

c) brittle and ductile

Explanation:

As we know that the fracture point is the point where the material breaks down while ultimate strength is the point at which maximum stress is sustained by the object.

If the fracture point occurs just after the ultimate strength then it shows that the material will break just after the maximum stress applied on it

But if the fracture point occurs after long distance of ultimate strength then the body will not break immediately and this property is known as ductile property of the object

So here we can say

Material X is Brittle as the distance between ultimate strength and fracture point  is close to each other

Material Y is ductile as this material has long range of fracture point and ultimate strength.
