Figure shows the stress-strain curve of ...

Figure shows the stress-strain curve of two metals `P` and `Q`. From the graph, it can be concluded that

A

(A) P has greater young's modulus and lesser ductility

B

(B) Q has greater young's modulus and lesser ductility

C

(C) P has greater young's modulus and greater ductility

D

(D) Q has greater young's modulus and greater ductility

Text Solution

Verified by Experts

The correct Answer is:
A
In the figure , the reciprocal of slope of stress - strain (x and y- axes ) curve , upto proportionality limit, gives young's modulus. The measure of ductility is obtained as the length of the stress-strain curve between yield point and ultimate load.
