Question

In plotting stress versus strain curves for two materials $P$ and $Q$, a student by mistake puts strain on the $Y$-axis and stress on the $X$-axis as shown in the figure. Then, which of the following statement(s) is/are correct? Stress

• A. $P$ has more tensile strength than $Q$.
• B. $P$ is more ductile than $Q$.
• C. $P$ is more brittle than $Q$.
• D. The Young's modulus of $P$ is more than that of $Q$.

Answer 1

Answer: (B)

From given graph, $P$ has more strain for same stress as on $Q$, so $P$ is more ductile than $Q$.
Thus, the statement given in option (b) is correct, rest are incorrect.
