Harmonic Oscillator: Damped and Forced

This lecture covers the analysis of harmonic oscillators, including damped and forced oscillations. It explains the impact of damping and external forces on oscillatory motion, as well as resonance phenomena. The instructor discusses the solutions to the differential equations governing these systems and explores different damping regimes. The lecture also delves into the concept of resonance, highlighting its effects and applications in various fields such as horology, signal filtering, and musical instruments. Additionally, it addresses the undesirable consequences of resonance in structures and vehicles, emphasizing the importance of dampers to mitigate these effects.
