Question

Which of the following material doesn't follow Hooke's law?
1. Steel
2. Aluminium
3. Rubber
4. All of the above Hook's law

Answer 1

Correct Answer - Option 3 : Rubber

CONCEPT:

• Elastic materials are the material which after deformation can regain their original shape and size.
• Elastic materials follow Hooke's law.
• Elastomers: The materials that can be stretched to cause large strains are called elastomers.
  • Elastomers don't follow Hooke's law.

EXPLANATION:

• Steel and Aluminum are elastic materials. So they will follow Hooke's law.
• Rubber is an elastomer. So it will not follow Hooke's law.
• So the correct answer is option 3.
