On the lever law of Archimedes in the mechanics of bodies
AbstractThe lever law of Archimedes is widely known since classical antiquity. It is used in many practical applications. Ample experience confirms its validity. Therefore, the lever law sometimes appears obvious or trivial. Its manifestation in the literature of physics ranges from common ignorance through rare marked appreciation to erroneous ...

Direction of Spontaneous Processes in Non-Equilibrium Systems with Movable/Permeable Internal Walls [PDF]
We consider three different systems in a heat flow: an ideal gas, a van der Waals gas, and a binary mixture of ideal gases. We divide each system internally into two subsystems by a movable wall.

Negligible contribution of body density to in-water vertical jump performance in elite male water polo players. [PDF]
The aim of this study was to investigate the associations among in-water vertical jump and various dry-land physical measures by taking the law of Archimedes into consideration, and by normalizing the dry-land measures both to body density and body mass.
