The free oscillations of Jupiter
Planetary and Space Science, 1999Abstract The spectrum of free oscillations of Jupiter is calculated for a set of models, each of them fitting all available observational data. Diagnostic capabilities of the spectrum are studied. They could be used, as soon as relevant observations are performed, for both the identification of the observed modes and the improvement of the models ...

Theoretical studies are made on the free oscillation of a homogeneous self-gravitating elastic sphere. Numerical results for torsional and spheroidal oscillations are shown in Tables 1 and 3, respectively. In these tables, are shown also the free periods of a model moon, for which density ρ = 3.33 g/cm and shear wave velocity V8 = 4.7 km/sec.

On the free Oscillations of Spheroids
Physical Review, 1920Oscillations of liquid drops, assuming the potential energy for any momentary form to be that due to capillarity only. Rayleigh's method of energy is applied so as to yield a formula for the frequency of oscillation for cases where the momentary surface differs from that of equilibrium by a spherical harmonic deviation of arbitrary order and rank.

On free oscillations of the earth
Geophysical Surveys, 1974This survey concerns mostly the theory of free oscillations, with a section on experimental work included at the end. Developments over the last 15 years are examined. The general theory of free oscillations is reviewed, and the effect on free oscillations of such factors as heterogeneity, the Earth's rotation and non-sphericity, and the source of the ...

This chapter is concerned with damped oscillators. Nonlinear oscillators are mainly dealt with, but linear oscillators are also considered or referred to for the sake of comparison or clear extension of the related methodology. First, Lagrangians and conservation laws of viscously damped linear oscillators as well as Duffing oscillators are presented ...

Free oscillations of the Earth: 1. Toroidal oscillations
Journal of Geophysical Research, 1960The free periods of toroidal oscillations of the earth have been computed for two earth models. The lowest period for the Gutenberg model earth is 2651 sec and for the Jeffreys-Bullen model 2732 sec. The surface amplitudes of the oscillations have been computed for three kinds of delta function stress sources—a unit force, a unit couple, and a unit ...

This chapter introduces several equivalent mathematical expressions for the oscillation of a physical system and shows how one expression can be transformed into another. The expressions involve the following concepts: amplitude, frequency and phase. The motion of a mass attached to one end of a spring is described by Newton’s laws.

In this chapter the aim is to describe the oscillatory behaviour of a simple system when vibrating freely, that is, without any external influences after the initial start-up.
