Physics
A spring couples vertical motion to twist. Adjust inertia to match the uncoupled frequencies and observe energy exchange, damping and split normal modes.
Tune the two frequencies, then watch energy trade between bounce and twist.
Equations m z" = -k z - c θ - m γ z' I θ" = -κ θ - c z - I γ θ' E = (m z'² + I θ'² + k z² + κ θ²)/2 + c z θ
Physics
Five pendula exchange forces through a moving board. Each has a smooth self-sustaining escapement; mass, detuning and clamping change the measured phase coherence.
Physics
Five ideal mechanisms turn rotation into indexing, lift, reciprocation or offset-shaft transmission. Inspect the computed displacement and speed.
Physics
A pendulum regulates an ideal anchor escapement. Event-based impulses replace dissipated energy, while measured tick intervals reveal the dependence on length and amplitude.
