Question : Which law was discovered in 1660, which states that for relatively small deformations of an object, the displacement or size of the deformation is directly proportional to the deforming force or load?
Option 1: Charles's law
Option 2: Avogadro's law
Option 3: Hooke's law
Option 4: Bragg's law
Correct Answer: Hooke's law
Solution : The correct option is Hooke's law .
Hooke's law was first formulated in 1660 and states that, for relatively small deformations of an object, the displacement or size of the deformation is directly proportional to the deforming force or load. Mathematically, Hooke's Law is often expressed as F = k⋅x, where:
- F is the force applied to the object,
- k is the stiffness or elastic constant of the material, and
- x is the displacement or deformation of the object.
