Correct Answer - Option 1 : Ductile
According to Hooke’s law,
“For small deformation, the stress in a body is proportional to the corresponding strain.”
i.e. stress ∝ strain
or stress = (E) (strain)
Here, E is a constant called the modulus of elasticity.
Now, depending upon the nature of the deforming force applied on the body, stress, strain,
and hence modulus of elasticity are classified into the following three types:
1. Young's modulus
2. Bulk modulus and
3. Modulus of rigidity
- If a material having a large plastic region will be considered ductile.
- It means the material can be easily drawn into thin wire.
- This ductility property is also associated with the young's modulus of elasticity.
- The larger the value of young's modulus greater will be the ductility.
Hence, option - 1 is correct
