Question

According to Hooke?? 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

Answer: (D)

remains constant

Answer 2

According to Hooke?? law, within the elastic limit, stress is directly proportional to the strain i.e. Stress $\propto$ Strain or $\quad$ Stress = k strain $\frac{Stress}{Strain}=k$ where $k$ is the proportionality constant and is known as modulus of elasticity.
