Mechanics of Materials - Part 13 (Lateral strain and Poisson's ratio) | MOM | SOM | BME301

In this video, we provide a clear explanation of the differences between linear strain and lateral strain in a material subjected to normal stress. We look into the definitions and physical meanings of these types of strain, showing how they relate to the deformation of materials under load. Additionally, we introduce the concept of Poisson's ratio, a fundamental material property that describes the relationship between linear and lateral strains. By the end of this video, you'll have a solid understanding of how materials deform in different directions when subjected to normal stress and how Poisson's ratio is used to quantify this behavior. This video is perfect for students and professionals in engineering who want to strengthen their knowledge of material mechanics and the fundamental principles that govern deformation.
