Normal-force dependant friction in centrifugal pendulum
· A model of the normal-force dependant friction loss between the rotor and pendula is developed for bifilar centrifugal pendulum vibration absorbers (CPVAs). The normal-force is dominantly dependant on the rotor rotational velocity but also dependant on the pendulum path.

The Foucault Pendulum ScienceBits
The Foucault Pendulum was conceived by Léon Foucault in the middle of the 19 th century with the goal of proving Earth s rotation through the effect of the Coriolis Force.In essence the Foucault Pendulum is a Pendulum with a long enough damping rate such that the precession of its plane of oscillations can be observed after typically an hour or more.
