Q. The diagram shows stress $v/s$ strain curve for the materials $A$ and $B$. From the curves we infer that
A) $A$ is brittle but $B$ is ductile
B) $A$ ductile and $B$ is brittle
C) Both $A$ and $B$ are ductile
D) Both $A$ and $B$ are brittle
Explanation
(b) In ductile materials, yield point exist while in Brittle material, failure would occur without yielding
