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?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Hooke’s law
- The law discovered in 1660 that states for relatively small deformations of an object, the displacement or size of the deformation is directly proportional to the deforming force or load is known as Hooke's Law.
- This fundamental principle in physics and materials science was named after Robert Hooke, who first formulated it.
- Hooke's Law mathematically describes this relationship as F = -kx, where F represents the force applied, k is the spring constant or stiffness of the material, and x is the displacement or deformation.
- It's a fundamental concept in understanding the behavior of elastic materials like springs and is widely used in engineering and physics.
