Question

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), ductile and brittle, brittle and ductile, brittle and plastic, plastic and ductile
