This
animation illustrates the Archimedes principle, when applied to an
object
submerged in liquid and suspended from a dynamometer (graded spring).
The weight indicated depends on the volume of the object submerged,
its density
as well as that of the liquid itself. These values may be modified
at will (within certain
limits) using the corresponding zones. When "Enter" is pressed, all
data is
displayed relative to the weight of the object, the Archimedes upthrust
and
the weight measured by the dynamometer according to the volume of
liquid displaced. This value may be modified by increasing or decreasing
the submersion
depth of the solid object using the mouse. To conform to reality,
the force of gravity
applied is that present on earth at sea level. When the dynamometer
is subjected to
excessive tension, the message " maximum attained! " appears in red.
