Solid Mechanics Fundamentals: Trusses, Beams, and Shafts

Understanding how physical structures bear loads and resist forces is the cornerstone of civil, mechanical, and structural engineering. This text-based course guides you through the core principles of solid mechanics, giving you the analytical tools to evaluate real-world structures. You will transition from basic physics concepts to confidently calculating internal responses in load-bearing components. By working through this comprehensive material, you will build a strong foundation in structural analysis, learning how to determine exactly how materials behave under tension, compression, bending, and torsion. What you'll learn: - Understand foundational concepts of stress, strain, and material equilibrium. - Calculate internal axial forces in the members of truss structures using joint and section methods. - Determine internal shear forces and bending moments in beams under various loading conditions. - Construct shear and moment diagrams to locate critical stress points in structural members. - Analyze torsional shear stresses and internal moments in rotating shafts. - Apply modern safety factors and limit-state design principles to structural evaluations. This course begins with essential definitions of forces and static equilibrium before moving into detailed structural analysis. You will progress systematically from simple truss structures to more complex beams and shafts, supported by clear written derivations and practical calculation exercises. This course is designed for beginners, engineering students, and professionals seeking a clear, text-based refresher on structural mechanics. No advanced engineering background is required, though a basic understanding of high school algebra and physics is helpful.
