हिन्दीThe 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),
Correct answer · Option 3
Brittle and ductile
Explanation
For brittle materials, fracture occurs soon after the elastic limit (close ultimate and fracture points). For ductile materials, there is a large plastic deformation region between ultimate strength and fracture points.
