The term liquid crystal refers to a state that is intermediate between

Liquid crystals are materials that exhibit properties between solids and liquids. They flow like liquids but have an ordered molecular structure similar to solids. Used in displays, sensors, and optical devices, liquid crystals change orientation in response to electric fields, enabling their widespread application in modern technology like LCD screens.

Class 11 Physics Chapter 8 covers mechanical properties of solids including stress strain relationships Young’s modulus bulk modulus and shear modulus. It explains elasticity Hooke’s law factors affecting elasticity and applications in engineering and materials science. This chapter emphasizes the importance of understanding solid mechanics for real-world applications like construction and material selection.
