LMEC-7 Pohl’s Pendulum

Experiments 1. Measure the damping coefficient of cycloid vibration and study the influence of different damping on vibration 2. Study the influence of different period dynamic moment on forced vibration and observe resonance phenomenon 3. Measure the amplitude frequency characteristics and phase frequency characteristics of forced vibration
