Question

Hooke's law defines

• A. stress
• B. strain
• C. modulus of elasticity
• D. elastic limit

Answer 1

Answer: (C)

According to Hooke's law, within the elastic limits stress is directly proportional to strain.
i.e. $stress\propto strain$ or $\frac{stress}{strain}=constant=E$
The constant $E$ is called the modulus of elasticity.
