This property quantifies how much a material resists changes in volume under pressure.
The CBSE syllabus for 2024-2025 includes Chapter 8 “Mechanical Properties of Solids” from the Class 11 NCERT Physics textbook. This chapter covers essential concepts like stress, strain, elasticity, Young’s modulus, bulk modulus, shear modulus and Poisson’s ratio. It explains how solids deform under different types of forces and the factors that influence their mechanical properties. Multiple-choice questions help assess understanding of these principles such as Hooke’s Law and the stress-strain relationship. Understanding these concepts is crucial for both academic knowledge and real-life applications in various fields like engineering and materials science.

The material property that measures resistance to compression is called **compressive strength**.
Compressive strength is defined as the maximum compressive stress a material can withstand before it fails or deforms permanently. It is typically measured by applying a compressive force to a specimen of the material in a controlled manner, often using a testing machine. The results are expressed in units of pressure, such as Pascals (Pa), megapascals (MPa), or pounds per square inch (psi).
Materials with high compressive strength, such as concrete, steel, and ceramics, are commonly used in construction and engineering applications where resistance to compression is critical.
