Equilibrium in a Damped, Heteroparametrically Driven Simple Pendulum

Abstract

The object of this SIP was first to experimentally obtain an equilibrium state between the energy that is being pumped into the pendulum's swing via a periodic variation of its length and the energy that is lost to air resistance experienced by the pendulum bob. Secondly, the object was to explain the experimental result's by means of a computer simulation of the system.
