Question

Hooke’s law states that
(a) Stress is directly proportional to the strain
(b) Stress is inversely proportional to the strain
(c) Stress is proportional to Young’s modulus
(d) Stress and strain are independent of each
other

Answer 1

Answer:

Option a)Stress is directly proportional to strain

Answer 2

Hooke's law states that Stress and Strain are directly proportional to each other.

• Mathematically, Hooke's law can be expressed as

F = -kx,

        where F is the force acting on an elastic object, x is the distance moved by it (extension), and k is the spring constant.

• According to the law, the strain acting on an elastic body is proportional to the amount of stress applied to it. The law is valid, provided that the extension is within the material's elastic limit.
• If the material gets stretched beyond this limit, the stress-strain proportionality changes.
