Structural Mechanics Fundamentals

This lecture introduces the fundamental concepts of structural mechanics, focusing on systems of forces in 2D. The instructor explains the classification of forces, the concept of resultant force, and the prediction of object responses to loads. Topics covered include deformable bodies, solid mechanics, mechanical equilibrium, external forces, and typical structural materials and elements. The lecture also discusses Saint Venant's Principle, CAD, Finite Element Analysis, and the principles of rigid bodies. Practical examples and calculations are provided to illustrate the application of these concepts.
