Derivation of Pendulum equations method 4

The video tutorial explains how to calculate the equations of motion for a pendulum using the sum of torques and moment of inertia. It begins with an introduction to the method, followed by creating a free body diagram to analyze forces. The tutorial then covers torque calculation, moment of inertia, and concludes with deriving the final equation for pendulum motion.
