1. Experiments on the variation of undamped natural frequency with vibrating mass
2. The effect of viscous damping on free vibration and the determination of the damping ratio c
3. Forced vibrations excited by oscillating the support.
4. Forced vibrations excited by rotating out-of balance forces.
5. The response of the vibrating mass to forcing, illustrating the decay of the transient vibration and the establishment of the steady state vibration.
