Equilibrium 2D II: Constraints and Statical Determinacy

This lecture covers boundary conditions in 2D, including supports and joints, as well as the concept of Free-Body Diagrams (F.B.D.). It delves into Constraints and Statical Determinacy, exploring the number of supports and joints required for equilibrium and addressing scenarios with more or fewer supports. Through examples like a system of pulleys, the instructor illustrates the application of these concepts in structural mechanics, emphasizing the importance of accurately modeling joints and supports in Free-Body Diagrams to analyze forces and moments effectively.
