The diagram shows stress versus strain curve for the materials \(A\) and \(B\). From the curves, we can infer that
\(A\) is brittle but \(B\) is ductile
\(A\) is ductile but \(B\) is brittle
Both \(A\) and \(B\) are ductile
Both \(A\) and \(B\) are brittle
Solution
According to stress-strain curve, we see that for same value of applied stress, strain produced is more in material \(B\) than in material \(A\) in linear region. Therefore, \(A\) is ductile but \(B\) is brittle. In ductile materials, yield point exists whereas in brittle material failure occurs without yielding. \(A\) has yield point hence it is ductile. \(B\) doesn't have yield point hence \(B\) is brittle.
