The Trammel of Archimedes theorem says that the end of the red line (with distance from the yellow point equal to half of the length of the major axis) always lies on the ellipse. The line is automatically redrawn so that it intersects the major axis at a distance equal to half of the difference of the length of the two axes from the yellow point. Click and drag the yellow point to move it along the minor axis. Similarly, each red line has length equal to half of the length of the major axis. The Trammel of Archimedes theorem says that this point always lies on the ellipse. The black point on each blue line is a distance equal to half the minor axis from the green point. Click and drag the green point to move this line along the major axis the other end is automatically drawn to stay on the minor axis. Each blue line has length equal to half the sum of the length of the major axis and the minor axis. The three blue dots determine the position of the centre, the major axis and the minor axis. It is related to an elipsograph - Preceding unsigned comment added by 50.82.110.The Trammel of Archimedes The Trammel of Archimedes It can also be used to make a circle: sources: numberphile channel Bueatiful Trigonometry on youtube(June 16, 2020) Youtube: mathloger - secrets of the nothing grinder, december 2019. Preceding unsigned comment added by Veloman ( talk Originally discovered in the 13th century. It also has quite a few nicknames, and the most popular ones are. grinder, Trammel of Archimedes, theyve gone by all sorts of names, when used for drawing its an ellipsograph. It is called the trammel of Archimedes, however there is no evidence that the mechanism is actually somehow related to the legendary Greek scholar. Unless you find its movement satisfying-to-watch, then it’s the best thing in the world. I believe this is properly described as a Tusi Couple which has it's own page. This machine was invented to draw ellipses, but other than that it’s kind of useless. woodworking or metalworking, the machine most definitively serves a useful purpose. Seeing how the trammel is (other than construction with a piece of rope and two nails) the only known way of -precisely- manufacturing an ellipse in e.g. The article suggests by its references (both forward and backward) that the trammel is a useless machine. contribs) That's a good question (which I don't know the answer to, unfortunately.) You may want to try asking over at the Reference desk.Is Archimedes credited with inventing the device, or simply describing the underlying principles of the ellipse? - Preceding unsigned comment added by 71.94.157.242 ( talk The article links to Archimedes without any explanation of the historical context of the Trammel of Archimedes.
