Hooke's law defines

A
stress
B
strain
Correct answer
C
modulus of elasticity
D
elastic limit

Solution

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.

Hence, the correct answer is option: 'C'.
