In elastic region, the slope of the stress-strain curve gives the value of Correct Answer Elastic modulus

The correct answer is option 2) i.e. Elastic modulus.

CONCEPT:

  • Stress-strain curve: It is the curve representing the relationship between stress and strain.
    • The curve is obtained by applying different amount of loads(stress) on a test material and recording the respective deformation(strain) in the load.
    • The curve is useful in estimating the different properties of a material such as Elastic modulus, yield strength, ultimate tensile strength, etc.

Additional Information

  •  The slope of the curve in the plastic region will give the value of the elastic modulus.
  • Poisson's ratio is the ratio of transverse strain to axial strain.
