Question

According to Hooke's law of elasticity, if stress is increased, the ratio of stress to strain

• A. decreases
• B. increases
• C. becomes zero
• D. remains constant

Answer 1

The correct option is D remains constant

According to Hooke's law, within the elastic limit, stress is directly proportional to the strain:

i.e., $stress\propto strain$
or $Stress=k\times strain$
$\frac{stress}{strain}=k$
where $k$ is the proportionality constant and is known as modulus of elasticity.
