Mechanics of Materials: Elongation Under Self-Weight

Every physical component has weight, and under its own mass, it experiences internal stress and deformation. Understanding how to calculate this self-weight elongation is a fundamental skill for civil, structural, and mechanical engineers. This text-based course guides you through the core principles of mechanics of materials, specifically focusing on axial deformation caused by self-weight. You will transition from basic concepts of stress and strain to deriving and applying elongation formulas for uniform and tapered bars. What you'll learn: 1. Understand the fundamental principles of stress, strain, and Hooke's Law under axial loading. 2. Derive mathematical formulas for elongation due to self-weight in both prismatic and conical bars. 3. Analyze how material density, length, and elasticity influence structural deformation. 4. Practice calculating total elongation under combined loading conditions, including self-weight and external axial forces. 5. Apply structural analysis concepts to evaluate real-world engineering scenarios. Starting with key terminology and foundational material properties, the course walks you through step-by-step mathematical derivations and practical written exercises. Designed for beginners in engineering, physics students, and anyone looking to build a strong foundation in structural mechanics, this course requires no advanced prerequisites.
