Structural Mechanics Fundamentals

This lecture introduces the fundamental concepts of structural mechanics, focusing on the prediction of how objects respond to loads and the analysis and design of mechanical systems. Topics covered include basic mechanics vocabulary, materials properties, stress and strain, equilibrium of forces and moments, and elementary structures like bars, cables, trusses, and beams. The history of mechanics, from point particle mechanics to 3D continuum mechanics and linear elasticity, is also discussed. Additionally, the lecture explores concepts such as hyperelasticity, viscoelasticity, plasticity, and fracture in materials. Practical applications and examples, such as the Eiffel Tower's design principles, are used to illustrate key concepts.
