Classical rotational inertia of solid 4He.
The observation of reduced rotational inertia in a cell containing solid 4He has been interpreted as evidence for superfluidity of the solid. We propose an alternative explanation: slippage of the solid, due to grain boundary premelting between the solid and dense adsorbed layers at the container wall. We calculate the range of film thickness, and determine the viscosity that will account for t...
متن کاملObservation of Non-classical Rotational Inertia in Solid Helium - an Indication of Superflow in Solids?
The phenomenon of Non-Classical Rotational Inertia, in which a body does not rotate with its rotating container, has been recently observed in solid Helium-4. This property is shared by superfluid liquid helium. The recent findings might be evidence of superflow in solids. Superfluidity or flow sans dissipation is commonly associated with liquids. Counter-intuitive as it may seem, quantum mecha...

متن کاملRotational propulsion enabled by inertia.
The fluid mechanics of small-scale locomotion has recently attracted considerable attention, due to its importance in cell motility and the design of artificial micro-swimmers for biomedical applications. Most studies on the topic consider the ideal limit of zero Reynolds number. In this paper, we investigate a simple propulsion mechanism --an up-down asymmetric dumbbell rotating about its axis...
متن کاملHuman Postural Model That Captures Rotational Inertia
INTRODUCTION Inverted pendulum models have been very beneficial for the modeling and analysis of human gait and balance [Kuo, 2007]. These reduced models allow us to ignore the movements of the individual limbs, and instead, focus on two important points -the center of pressure (CoP) and the center of mass (CoM) -and the lean line that connects the two points. A limitation of the existing reduc...
