Mechanical Properties of Solids - Important Formulas, Definitions, and Examples | 11th Physics
Chapter 6: Mechanical Properties of Solids Chapter 6: Mechanical Properties of Solids Formulas: Stress, Strain, Hooke’s Law, Young’s Modulus, Bulk Modulus, Shear Modulus Introduction This chapter explores the mechanical behavior of solid materials when subjected to different types of forces. The study of the mechanical properties of solids includes concepts like stress, strain, and elastic behavior, governed by Hooke's Law. These properties are essential for understanding how materials deform under force and how they return to their original shape when the force is removed. 1. Stress and Strain Definition: Stress is the internal restoring force per unit area that develops within a material when an external force is applied. It is measured in Pascals (Pa). Formula: Stress (σ) = Force (F) / Area (A) Strain is the relative change in the shape or size of a material as a response to stress. It is a dime...
