Torsional Oscillation of Shafts
Aircraft Engineering and Aerospace Technology, 1936THE force couples, including moments due to inertia masses, which acting at different points on a crankshaft cause an elastic distortion, as a result of which points disposed in the axial plane are subject to an angular displacement in relation to one another in the form of a phase advance and retard movement, and it follows that each will possess a ...

On Torsional Oscillations of Wires
Proceedings of the Royal Society of Edinburgh, 1899AbstractThis paper is in continuation of two others, on the same subject, previously communicated to the Society. It consists of two parts, the first experimental, the second theoretical.The wire which was experimented upon was the one which was used in the previous experiments, and the apparatus was that described in the latter of the communications ...

High-frequency torsional oscillations—I
International Journal of Engineering Science, 1978Abstract The Reissner-Sagocci Problem at high-frequencies for an elastic medium with exponentially varying shear modulus and density in the radial direction is asymptotically reduced to a Wiener-Hopf integral equation whose solution is obtained by Carleman's method. Uniform asymptotic results are obtained.

Magnetostrictively induced torsional oscillations
Journal of Scientific Instruments, 1966Experiments have been made on the Wiedemann effect when one of the applied magnetizing forces is oscillatory. With the ferromagnetic specimen immersed in fluids of viscosities between 0.37 and 21.05 CP the impedance-frequency characteristics have been investigated in the region of the resonant frequency.

The Spectrum of Torsional Oscillations of the Moon
Solar System Research, 2000The diagnostic potentialities of the torsional oscillations for probing the structure of the interiors of the Moon are investigated. Models with no core, a liquid core, and a solid core are considered. The profiles of compressional and shear wave velocities VP and VS for the lunar interior estimated by Bills and Ferrari (1977), Goins et al. (1981), and

Torsional oscillations of low mode
Solar Physics, 1985Standing wave torsional oscillations of wavenumber 1/2 and 1 hemisphere−1 are studied using an improved fit to Mount Wilson magnetograph data. These oscillations are seen to be in phase with each other and with the magnetic activity cycle, and seem best represented as a flexing of the differential rotation curve.

Torsional Oscillations in Moving Bands
Journal of Vibration and Acoustics, 1988The torsional vibration of moving bands subject to harmonic tension fluctuation is investigated. A thin rectangular strip translating longitudinally with a constant speed and simply supported at its end is considered. The linearized equation of motion, when suitably discretized, represents a linear gyroscopic system with periodically varying stiffness.

Neutrino oscillations in the presence of torsion
Il Nuovo Cimento A, 1981In this paper we consider the influence of torsion on neutrino oscillations: if we allow for lepton number nonconservation and the possibility of flavour mixing in a space with torsion, it follows that the phenomenological neutrinos produced in the charged-current weak interactions are not, in general, the eigenstates of the torsional Hamiltonian, and ...

Magnetic Torsional Oscillations in Magnetars
AIP Conference Proceedings, 2009We investigate torsional Alfven oscillations of relativistic stars with a global dipole magnetic field, via 2D numerical simulations. We find that a) there exist two families of quasi‐periodic oscillations (QPOs) with harmonics at integer multiples of the fundamental frequency, b) the QPOs are long‐lived, c) for the chosen form of dipolar magnetic ...

Torsional oscillations and the solar cycle
Solar Physics, 1987Both the net torsional pattern and its derivative, the shear oscillation, are studied in relation to the solar activity cycle using data collected at Mount Wilson from 1967–1986. The shear is seen as the better quantity for study, since it is both more fully determinable with these data and has straighter ties to the zones of activity.
