“Hidden” Momentum in a Linked Pair of Gyrostats?
نویسندگان
چکیده
A gyrostat is a massive sphere (or disk) mounted such that the supporting apparatus exerts no torque about the center of the sphere. The earliest gyrostat was described by Bohnenberger [1] in 1817, as shown below. The name gyroscope was applied to this apparatus by Foucault [2] in 1852, although this term has come to imply a sphere or disk mounted with a fixed point on its axis. Lord Kelvin used the term gyrostat in 1874 [3], but in the more modern sense of gyroscope.

Study of lone pair description in molecules by the modified delocalized floating spherical Gaussian orbital method.
This research has been carried out to study and find a rather general description for a lone pairorbital in molecules. Since the orbital parameters must be manageable in advance, and correctgeometry of the molecule (bond lengths) is depend on the appropriate lone pair description; theFSGO method including optimization has been used to obtain orbital parameters and energy. Theproposed models for...
متن کاملOn the Relation between Energy-Conserving Low-Order Models and a System of Coupled Generalized Volterra Gyrostats with Nonlinear Feedback
In this paper we first prove the equivalence between the system of coupled Volterra gyrostats and a special class of energy-conserving low-order models. We then extend the definition of the classical Volterra gyrostat to include nonlinear feedback, resulting in a class of generalized Volterra gyrostats. Using this new class of gyrostats as a basic building block, we present an algorithm for con...
متن کاملIdentification of a sex-linked SCAR marker for Plecoglossus altivelis and its application for identifying gender in cultivated and wild populations
Ayu (Plecoglossus altivelis), one kinds of valuable cultured fish species, show almost no morphological difference between male and female until sexual maturity. Here, we report the identification of sex-linked markers for the ayu, based on Amplified Fragment Length Polymorphism (AFLP) generated from cultured fish (15 males and 15 females) by using 63 different primer combinations. Genomic frag...
متن کاملSpinup Dynamics of Gyrostats
Attention is given to the spinup dynamics of gyrostats containing a single axisymmetric rotor. Spinup of the rotor is due to a small constant torque applied by a motor on the platform. The dynamics are described by four firstorder differential equations, which are put into noncanonical Hamiltonian form. Using conservation of angular momentum and the method of averaging, the equations of motion ...
