Cantilever Beam and Principal Parametric Resonance — Lesson 1

This lesson covers the final module of a course on non-linear vibration, focusing on its various applications. The module is divided into nine classes, each exploring different types of applications. The lesson particularly emphasizes the study of flexible non-linear systems, non-linear vibration observers, and electromechanical systems. The first class delves into non-linear flexible systems, explaining that all systems are inherently flexible. The lesson also discusses the challenges of dealing with rigid structures, such as their bulkiness, heavy inertia force, and the large torque or force required to activate them.
