The stress-strain curves are drawn for two different materials X and Y . It is observed that the ultimate strength point and the fracture point are close to each other for material X but are far apart for material Y. We can say that materials X and Y are likely to be (respectively)

Options

  1. Aductile and brittle
  2. Bbrittle and ductile
  3. Cbrittle and plastic
  4. Dplastic and ductile

Correct answer

B. brittle and ductile

Step-by-step solution

The stress-strain curve for a material is shown This curve specifies the behaviour of material. For the material, if distance between strength point and fracture point is small, so it is brittle and will break easily on the application of some extra stress after point D. For material Y , if the distance between strength point and fracture point is large, so it is a ductile material and can withstand for some extra stress beyond point D .
