Archimedes' principle of confusion regarding Archimedes' principle is the meaning of displaced volume. Common demonstrations involve measuring the rise in water level when an object floats on the surface in order to calculate the displaced water. This measurement approach fails with a buoyant submerged object because the rise in the water level is directly related to the volume of the object and not the mass (except if the effective density of the object equals exactly the fluid density). (note that this idea is not Archimedes' principle). Archimedes' principle Archimedes' principle states that the upward buoyant force that is exerted on a body
Trammel of Archimedes in the form of the standard parametric equations for an ellipse in canonical position. The further equation is immediate as well. The trammel of Archimedes is an example of a four-bar linkage with two sliders and two pivots, and is special case of the more general oblique trammel. The axes constraining the pivots do not have to be perpendicular and the points "A", "B" and "C" can form a triangle. The resulting locus of "C" is still an ellipse. Trammel of Archimedes A trammel of Archimedes is a mechanism that generates the shape of an ellipse. It consists of two
