Equilibrium in 3D: Structural Mechanics Fundamentals

This lecture covers the fundamentals of equilibrium in 3D structures, including the definition of equilibrium conditions, constraints, and statical determinacy. It also explores the concept of hyperstatic and hypostatic systems, the adequacy of constraints, and the use of linear algebra to analyze equilibrium. The lecture delves into the concept of the instantaneous center of rotation, types of supports, and categories of equilibrium in 3D, such as forces concurrent at a point or along a line. Additionally, it discusses the analysis of forces that are parallel and the constraints imposed by different types of supports.
