Long answer type question.

Draw a labelled graph of tensile stress against tensile strain for a metal wire up to the breaking point. In this graph show the region in which Hooke’s law is obeyed.


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). 


The stress-strain graphs for two materials are shown in figure (assume same scale).


Material (i)

Material (i)
  1. Material (ii) is more elastic than material (i) and hence material (ii) is more brittle.
  2. Material (i) and (ii) have the same elasticity and the same brittleness.
  3. Material (ii) is elastic over a larger region of strain as compared to (i).
  4. Material (ii) is more brittle than material (i).
