These are examples of tensegrities
in 2d. Tensegrities are structures in self-equilibrium that I
studied in the paper From
graphs to tensegrity structures: Geometric and symbolic approaches,
Miguel de Guzmán. Example 3.8 of that paper is the first
The rest of constructions study the possible tensegrities for
graphs on 8 vertices.
In the constructions red
edges are springs with resting length of zero, while blue
have positive resting length. You are invited to move freely the points
and then push the "play" button to see the resultant tensegrity. All of
these constructions were created
using Cinderella 2.
