Pendulum Systems: Constraints and Forces

This lecture covers the analysis of pendulum systems, focusing on constraints, forces, and reference frames. It discusses cylindrical coordinates, rotational motion, and the impact of constraints on the system's behavior. The instructor explains the relationship between tension, acceleration, and the pendulum's movement. Additionally, the lecture explores the effects of different constraints on the system, such as fixed coordinates and bond strengths. Mathematical structures and equations are used to model the behavior of pendulum systems under various conditions, including small oscillations and detachment scenarios.
