Pendulum Cascade

A chain of 12 rigid links, each half the length and mass of the one before. Forcing twists the first two links; energy cascades down the chain to the small links, where viscosity removes it.

The simulation integrates the true 1:2 chain. The drawing uses a gentler taper so the small links stay visible.
