Apparatus of Forced Vibration and Resonance for Mechanics Physics Lab

This Apparatus of Forced Vibration and Resonance for Mechanics Physics Lab is designed for studying the principles of forced vibrations, resonance phenomena, and frequency response characteristics in dynamic systems. The apparatus utilizes a tuning fork vibration system driven by electromagnetic excitation coils, while an integrated sensing system accurately monitors vibration amplitude. It enables users to investigate the relationship between driving frequency and vibration amplitude, analyze resonance behavior, and study the effects of mass loading and damping on oscillatory systems. The system provides a practical platform for understanding resonance applications in engineering, vibration analysis, and measurement technology.
