In plotting stress versus strain curves for two material P and Q, a student by mistake puts strain on the y-axis stress on ther x-axis as shown in the figure. Then the correct statement is/are

A

(a) P has more tensile strength than Q

B

(b) P is more ductile than Q

C

(c) P is more brittle than Q

D

(d) The Young's modulus of P is more than that of Q

Text Solution

Verified by Experts

The correct Answer is:
B, C
The maximum stress that P can withstand before breaking is greater than Q. Therefore (A) is a correct option.

The stain of P is more than Q therefore P is more ductile. Therefore (B) is a correct option.
`Y=(stress)/(strai n)`
For a given strain, stress is more for Q. Therefore `Y_QgtY_P`.
