The observation of reduced rotational inertia in a cell containing solid\nhelium 4 has been interpreted as evidence for superfluidity of the solid. An\nalternative explanation is slippage of the solid at the container wall due to\ngrain boundary premelting between the solid and dense adsorbed ...
effectively a disk rotating in a fluid, the resistive torque T is proportional to the angular velocityω and thus: T=cω=cdθdtwhere c is the damping constant. 3 Inertia The inertia of a rotational system is represented by the moment of inertia of a mass. A torque T applied to a ...

The rotational moment of inertia of a body has a radius of gyration Rg, which is measured relative to the body center of mass. One must integrate over the volume, which contains the solute particle. The above expression of Eq. (214) can be factored, which isolates the radius of gyration...
Homework Statement A gyroscope consists of a solid disk of diameter 1m and mass 100kg mounted on an axis passing through the center of mass of the disk. (a) Calculate the moment of inertia of the disk about its rotational axis. (b) What is the kinetic energy of rotation of the disk ...
These effects emerge as a particularity of the Fermi-Dirac statistics of electrons in rotating conductors. Keywords: mechanical rotation; rotational asymmetry; moment of inertia; electric conductivity1. Introduction Our daily-life experience tells us that any physical body has the same moments of ...
Okay? Remember also that if you have a shape or a rigid body, an object with non-negligible radius and volume, we're going to get the moment of inertia from a table lookup. For example, if you have a solid cylinder or a solid disk, same thing, the equation for that is ...
