Demonstrating Resonance

What happens here

David then describes the next phase of the demonstration: 'I can bring the frequency down to match the mount's frequency and create resonance.' As the forcing frequency is adjusted, a dramatic change occurs. The football players and goalposts, which were previously stationary, now begin to shake and move significantly. The loose objects on the lower platform continue to move, but the upper field's movement clearly demonstrates the effect of resonance, where the system amplifies the vibrations when the forcing frequency aligns with its natural frequency. David exclaims, 'Now we got a game going on! Goalposts are moving, everything's moving.'

Goal: The vibration frequency is then adjusted to match the natural frequency of the mounts, causing the football players and goalposts on the upper platform to begin moving and shaking vigorously, illustrating the principle of resonance.
