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

Remains constant

Explanation

Solution

: According to Hooke’s law with in the elastic limit, stress is directly proportional to the strain

i.e. Stress $\propto$ Strain

or Stress = k strain

$\frac{Stress}{Strain} = k$

Where k is the proportionality constant and is known as modulus of elasticity.
