Oscillations of a Physical Pendulum Having Cavities Filled with a Viscous Fluid

Abstract

An asymptotic method was proposed (1) for investigating the nonstationary motions of viscous incompressible fluids with large Reynolds numbers (NRe), which arise during the oscillation of various solids which either contain a fluid or are immersed in one, and also during the oscillation of liquid volumes having a free surface. In this article the idea of this method is applied to the investigation of small oscillations of a physical pendulum having cavities completely filled with an incompressible viscous fluid.
