Apparatus of Forced Vibration and Resonance Lab Experiments

This apparatus is designed for studying resonance phenomena in a tuning fork vibration system. It enables the investigation of resonance curves, damping effects, frequency variations due to mass changes, and the measurement of unknown masses through resonance analysis. Manufactured by Atico Export India.
Experiments:

1. Resonance Curve and Q-Factor Measurement

• Study resonance characteristics of a tuning fork under periodic driving forces
• Plot resonance amplitude versus frequency curves
• Determine the resonance frequency and quality factor (Q)
• Investigate energy storage and dissipation in resonant systems

2. Frequency-Mass Relationship Investigation

• Study the relationship between vibration frequency and tuning fork arm mass
• Analyze frequency shifts caused by attached masses
• Measure unknown masses using resonance-based methods
