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.
