According to Hooke’s law of elasticity, if stress is increased, the ratio of stress to strain

A law is a statement based on consistent observations and experiments that describes a natural phenomenon or relationship. It is universally applicable under specific conditions and serves as a foundation for scientific understanding. Laws are fundamental in explaining physical behaviors and are expressed mathematically or in descriptive terms.

Class 11 Physics Chapter 8 discusses the mechanical properties of solids. It covers stress strain Hooke’s law elasticity plasticity Young’s modulus bulk modulus and shear modulus. The chapter explains how solids deform under external forces and focuses on stretching compressing bending and the factors affecting the elasticity of materials.
