In plotting stress versus strain curves for two materials P and Q , a student by mistake puts strain on the y -axis and stress on the x - axis as shown in the figure. Then the correct statement(s) is(are)

  1. P has more tensile strength than Q
  2. P is more ductile than Q
  3. P is more brittle than Q
  4. The Young's modulus of P is more than that of Q

Solution

Slope of this graph represents the reciprocal of Young's modulus.
Since slope of P>  slope of Q
Hence Y of P<Y of Q `
