Solid Application: Rotating Bar

This lecture covers the application of rigid bodies, focusing on the falling of a bar and a physical pendulum. It discusses the forces involved, the pivot point, and the movement with respect to different reference frames. The lecture also delves into the equations of motion, the conversion to a system of first-order equations, and the numerical resolution. The analysis includes the integration by Runge-Kutta method and the visualization of the angular velocity. The instructor demonstrates the simulation of the falling bar and the pendulum using Python, discussing the initial conditions, the differential equations, and the numerical solutions. The lecture concludes with the graphical representation of the angle and angular velocity over time.
