About: Rhombic Triacontahedron (Internally supported)   Sponge Permalink

An Entity of Type : owl:Thing, within Data Space : 134.155.108.49:8890 associated with source dataset(s)

The rhombic triacontahedron is made from thirty golden rhombii, with the sharp ends meeting at twelve valency five nodes, and the shallow ends meeting in twenty valency three nodes. It is possible to build a rhombic triancontahedron "naked" with Geomag bars, but it is very unstable: the friction between the joins is just enough to keep the model afloat (TODO: picture). This model has an internal support structure that renders the solid rigid. The model is heavy (about 1kg) and strong: it's quite suitable for playing the game of Geomag Catch.

abstract
  • The rhombic triacontahedron is made from thirty golden rhombii, with the sharp ends meeting at twelve valency five nodes, and the shallow ends meeting in twenty valency three nodes. It is possible to build a rhombic triancontahedron "naked" with Geomag bars, but it is very unstable: the friction between the joins is just enough to keep the model afloat (TODO: picture). This model has an internal support structure that renders the solid rigid. This support structure is amazingly close (the error is less than 1%). It consists of five intersecting tetrahedra, connected to the spheres in the rhombic triacontahedron with valency 3 (there are twenty of them). The length of the tetrahedral edges is 3 rods. The model is heavy (about 1kg) and strong: it's quite suitable for playing the game of Geomag Catch.
