- Elastomers: The substances that can be stretched to cause large strains are called elastomers.
- Examples are the tissue of the aorta, rubber, etc.
- These materials do not obey Hooke’s law over most of the region.
- A typical stress-strain graph of an elastomer is given below:
Here we can clearly see that curve is not linear. To follow Hooke's law it is necessary that the curve should be in straight line.
EXPLANATION:
- Option 1: Plastic materials are the materials which when deformed does not return to their original state or show permanent deformation.
- Option 2: Elastic materials are the material which after deformation can regain their original shape and size.
- Option 3: The materials that can be stretched to cause large strains are called elastomers.
- So the correct answer is option 3.
