Question

The diagram shows stress vs. strain curve for the materials $A$ and $B$. From the curves we infer that

• A.
  Both $A$ and $B$ are birttle
• B.
  Both $A$ and $B$ are ductile
  
• C.
  $A$ is brittle but $B$ is ductile
  
• D.
  $A$ is ductile but $B$ is brittle
  

Answer 1

The correct option is D

$A$ is ductile but $B$ is brittle

In ductile materials, yield point exists while in brittle material, failure would occur without yielding.
