The stress - strain plot for wires made of two materials (I and II) is presented schematically in the accompanying figure. The points C_I and C_ I I represent fracture points of the two materials I and II respectively. It can be concluded from these graphs that

Options

  1. Amaterial I has Young's modulus larger than that of material II
  2. Bthe linear region of material I extends to a larger value of stress than that of material II.
  3. Cboth materials I and II are equally brittle.
  4. Dmaterial I is more ductile than material II.

Correct answer

D. material I is more ductile than material II.
