the cylinder until it becomes completely submerged. The increase in the level of
water inside the cylinder is simply equal to the volume of the object. This method, however, requires that the diameter of the cylinder be at least as large as PR6423002-001-CN
the diameter of the object, which reduces the accuracy of the measurement. In
addition, this method certainly cannot be used to measure the volume of a large
object such as a boulder. The problem, however, can be resolved by taking advantage of Archimedes’ principle. A container partially filled with water is
placed on a scale and the reading of the scale is recorded. The object is then
hung from a string above the water, and slowly lowered into it until it is completely submerged, but without touching the bottom of the container (if the object is less dense than water, it can be pushed under water). The reading of the
scale will increase by the mass of the displaced water (assuming that the scale PR6423002-001-CN
measures mass), from which the volume of the object can be determined [7]. Alternatively, the object can be hung above water from a scale. As the object is lowered into water, the reading of the scale decreases by an amount equal to the
mass of the displaced water. Thus, a boulder hanging from a spring or dial scale
can be lowered into a large volume of water, such as a pond or a lake, and from
the change of the reading of the scale, its volume can be determined.
Even though Archimedes’ principle is over 2200 years old and despite its importance in hydrostatics, there are still some questions about it that have not yet PR6423002-001-CN
been fully answered in the literature. For instance, debates are still going on regarding the interpretation of the principle when an object rests on the bottom of
a fluid-filled container, where it experiences a net downward force by the fluid.
It is therefore the objective of this article to derive the principle from a different
point of view and answer some of the questions associated with the principle
that have not been settled in the literature
