On the critical equilibrium of the spiral spring pendulum
Physical systems such as an inverted pendulum driven by a spiral spring, an unbalanced Euler elastica with a travelling mass, a heavy body with a parabolic section and an Ising ferromagnet are veryExpand

Chaos in Robert Hooke's inverted cone
Robert Hooke is perhaps one of the first scientists to have met chaotic motions. Indeed, to invert a cone and let a ball move in it was a mechanical model used by him to mimic the motion of a planetExpand

Amplitude equations for mechanical analogues of Faraday and nonlinear optical rotations
What is the relationship between the propagation of a light wave in a Kerr medium in the presence of a magnetic field and the oscillation of a spherical pendulum on a rotating platform? We apply theExpand
