... But one moves more easily than the others. Each corner of the tetrahedron needs three restraints to remove its translation and rotation freedoms. ... ...
Has there been an attempt to make a VE fullerne cage? Perhaps an icosa/dodeca of Carbon with some emplaced silicon (or other) atoms acting as jitterbug...
To my amusement, I found this, from Amy C. Edmondson in "A Fuller Explanation": ``Fig. 16-2. Hanging bookshelf, U.S. Patent 4,377,114 (1983). Click on...
... Indeed. So what? ... That is not true. For one thing, if you remove the translational freedoms of three non-colinear points on a solid object, then all...
... I had a look: ``I encountered the claim that it takes 12 spokes to stabilise a bicycle wheel hub with respect to the rim - if it was required that the hub...
Tim If you don't mind, can you show me two or three people explaining the seven-spokes-are-enough arguement(or some version of it)? Someone, an engineer maybe,...
... We are discussing the degree of motion available to a corner of a vertex, so I thought it is important to point out that in your seven restraints model,...
... Input from peers would be welcome. I discovered the seven cable configuration on 2006-02-19, announcing the fact on: http://listserv.buffalo.edu/cgi-bin/ ...
Offtopic, but this reminds me; I the other day thought out an Euler connection, assumed there might be an Euler 'law' that applies in a 3d volume. We know that...
... From: "Kirby Urner" <kirby.urner@...> [dels] ... Not really. I was hoping for an inclusion of sensible/standard physics within S., which apparently...
Thanks to all for the blast in my direction.... I take it back. Any "translation" would by now have been attempted, and I agree it would be pretty silly to...
... To expand: "Right - at least now I have some idea of what you are thinking". ... Right. So: you reject my notion of stability, and are proposing your own,...
... Quite correct Alan. I mispoke( in error ) not including a dividing line to the 6 edges. Thanks for keeping my straight friend. :) ... So do you see any...

Hold a stick. Use it to push away a snake. Use it to pull the snake towards you. Now try doing that with a rope. A stick is a coiled rope (spiraled cells...
Ahh Tim, laying here in bed I realized what your seven cable restraint does not take into account. Torque! And especially in regards to more spherical object...
... DD, me thinks compression is contraction( pulling-in ) force/motion and that all expansion( pushing-out ) forces/motions can only be a resulant of...
... So far no references to other previous work have been reported. That doesn't mean such work doesn't exist. On the other hand, while the question seems...
This particular incarnation of the twelve degrees of freedom topic started with someone's comments about Coxeter's new biography. Maybe you missed that. ... ...
