Bollt, Erik M.; Klebanoff, Aaron A new and simple chaos toy. (English) Zbl 1051.70013 Int. J. Bifurcation Chaos Appl. Sci. Eng. 12, No. 8, 1843-1857 (2002). Summary: We present two new, and perhaps the simplest yet, mechanical chaos demonstrations. They are both designed based on a recipe of competing nonlinear oscillations. One of these devices is simple enough that using the provided description, it can be built using a bicycle wheel, a piece of wood routed with an elliptical track, and a ball bearing. We provide a thorough Lagrangian mechanics based derivation of equations of motion, and a proof of chaos based on showing the existence of an embedded Smale horseshoe using Melnikov’s method. We conclude with discussion of a future application.
