Classical Mechanics: Finding Normal Modes for 3 Coupled Masses

This tutorial demonstrates the process of finding normal modes for a system of three masses connected by springs in classical mechanics. Learn the step-by-step approach to identifying these fundamental oscillation patterns, building upon concepts that may have been covered in previous videos about two-mass systems. The 22-minute video includes a complete mathematical walkthrough and features animated visualizations created with Python to help illustrate the behavior of coupled oscillators. Access to the Python code used for the animations is provided, allowing for further exploration and modification of the demonstrated concepts.
