Question
The stress versus strain graphs for two materials A and B are shown below:

(The graphs are to the same scale).

  1. Which material has greater Young's modulus?
  2. Which material is more ductile?
  3. Which is more brittle?
✓

Answer

  1. A, because for producing the same strain, more stress is required in case of the material A.
  2. A, because it has a greater plastic range.
  3. B, because it has a lesser plastic range.
