This course is designed specifically for students those have a bit lacking in core knowledge. The main idea behind these 7-8 lectures is to infuse in the minds of young ones, the fundamental concept behind strength of material. Topics covered are :- Stress strain relationship, true stress & strain, elastic constants, Bending & shearing stress, Beams & many more along with a bonus lecture containing important formulas & tips.
PS - Being a very old course,pardon the harsh sound quality.
This course is designed to provide a comprehensive exploration of the fundamental principles governing the mechanical behavior of materials. Students will delve into the intricate relationship between stress and strain, gaining a foundational understanding of material response under different mechanical loads. The course encompasses a diverse range of topics crucial to the field of Mechanics of Solids, ensuring that students acquire a thorough grasp of structural mechanics.
Course Coverage:
Stress-Strain Relationship: Students will be introduced to the concept of stress and strain, exploring the fundamental Hooke's Law and its practical applications. The course will also cover yield criteria and failure theories, providing insight into the limits of material strength.
Elastic Constants, True Stress & Strain: Delving into the elastic properties of materials, the course covers elastic constants such as Young's Modulus, Shear Modulus, and Bulk Modulus. True stress and true strain are examined, along with the significance of Poisson's ratio.
Plane Stress, Plane Strain & Mohr's Circle: Analysis of stress and strain in two dimensions is explored, along with the application of Mohr's circle for plane stress and strain. The practical implications of these concepts in design and analysis are discussed.
Bending & Shear Stresses: The course addresses the fundamentals of bending moment and shear force diagrams, along with the determination of bending and shear stresses in beams. Stress distribution in flexural and shear situations is examined in depth.
Second Moment of Inertia: Students will gain insight into the definition and significance of the second moment of inertia, exploring calculation methods for various shapes. The application of the second moment of inertia in bending and torsion scenarios is emphasized.
Beams: The different types of beams and supports are covered, along with the analysis of shear force and bending moment equations.
