Question

Which of the following correctly shows Hooke's law?

1.

stress ∝ strain

2.

stress ∝ strain²

3.

stress² ∝ strain

4.

stress ∝ 1/strain

Answer 1

Correct Answer - Option 1 :

stress ∝ strain

CONCEPT:

• Hooke's Law: For small deformations, the stress is proportional to the strain produced. 

Stress ∝ strain

stress = k × strain

where k is the proportionality constant.

EXPLANATION:

• According to Hooke's law stress is directly proportional to strain.

Stress ∝ strain

• So the correct answer is option 1.
