Introduction to Structural Mechanics

This lecture covers the fundamentals of structural mechanics, focusing on plane trusses, internal forces at joints, and the section method. The instructor explains the analysis of trusses, frames, and mechanisms, emphasizing the importance of equilibrium and the computation of internal forces. The lecture also delves into the concept of rigid structures and the strategy to solve problems using the joints method. Various examples of truss structures are presented, illustrating the application of theoretical concepts to real-world scenarios.
