The Foucault Pendulum (with a Twist)
A Foucault pendulum is supposed to precess in a direction opposite to the earth’s rotation, but nonlinear terms in the equations of motion can also produce precession. The goal of this paper is to study the motion of a nonlinear, spherical pendulum on a rotating planet. It turns out that the problem on a fixed energy level reduces to the study of a monotone twist map of an annulus. For certain ...
متن کاملSeismic shear waves as Foucault pendulum
Earth’s rotation causes splitting of normal modes. Wave fronts and rays are, however, not affected by Earth’s rotation, as we show theoretically and with observations made with USArray. We derive that the Coriolis force causes a small transverse component for P waves and a small longitudinal component for S waves. More importantly, Earth’s rotation leads to a slow rotation of the transverse pol...
متن کاملElastic waves as a Foucault pendulum?
The rotation of the Earth leads to a change in the equation of motion because of the Coriolis force. We study how Earth’s rotation affects elastic wave propagation. We show that the Coriolis force does not deflect seismic rays because the medium that carries the waves moves with Earth’s rotation. However, Earth’s rotation causes a weak traverse component of P-waves and a weak longitudinal compo...
متن کاملFrom the Foucault pendulum to the galactical gyroscope and LHC
The Lagrange theory of particle motion in the noninertial systems is applied to the Foucault pendulum, isosceles triangle pendulum and the general triangle pendulum swinging on the rotating Earth. As an analogue, planet orbiting in the rotating galaxy is considered as the the giant galactical gyroscope. The Lorentz equation and the Bargmann-MichelTelegdi equations are generalized for the rotati...
