Maxwell stress in Rindler space and the Archimedes Law

Physical Review D, 2006
We construct a theory of Maxwell stresses in Rindler space, presenting both a noncovariant and a covariant formulation. The theory shows how the Maxwell stresses are modified by a nonvanishing acceleration of gravity and that the Maxwell stresses of an electromagnetic field produce a volume stress force which vanishes in an inertial frame.

The Archimedes law and electrocapillarity

Electrochimica Acta, 1994
Abstract For an ideally polarizable electrode it is found that among numerous volume Hansen excesses there exists one which is correlated with the Archimedes law and plays the role of the solution volume displaced due to occurrence of surface layer.

A bizarre application of Archimedes’ law

Physics Education, 2007
We describe an experimental set-up that is very easy to construct but which produces an unusual phenomenon which verifies Archimedes' law for gas.

A Spring, Hooke's Law, and Archimedes' Principle

The Physics Teacher, 2005
A mass on a spring is a simple and inexpensive device that can be used to demonstrate many important physics concepts. Almost all standard introductory physics lab manuals include at least one or two experiments with a spring.1,2 Most of these experiments explore Hooke's law and simple harmonic motion.

How did Archimedes discover the law of buoyancy by experiment?

Frontiers of Mechanical Engineering, 2016
After Archimedes and Vitruvius era, for more than 2000 years, it has been believed that the displaced water measurement of golden crown is impossible, and at his Eureka moment, Archimedes discovered the law of buoyancy (Proposition 7 of his principles) and proved the theft of a goldsmith by weighing the golden crown in water.

Archimedes law under bifurcations of solution and partial averaging of phenomenological variables

Computational Mathematics and Mathematical Physics, 2011
Summary: A model of the convective flow of a viscous fluid is proposed with regard to possible finite ``fluctuations'' of thermophysical characteristics in a neighborhood of branch points. A method for the analysis of the influence of averaging on the values of the phenomenological variables for the secondary flow and exact bounds on these values are ...
