Figure 21: Basic Tensegrity Structures
The four-strut, 12 (twelve) tendoned outside-in (negative) tetrahedron
showing the 4 outer vertex turbining.
The six-strut tensegrity, 18 (eighteen) tendoned outside-out (positive)
tetrahedron showing central-angle turbining.
The three-strut, 12 (twelve) tendoned tensegrity octahedron. The
three compression struts do not touch each other as they pass at the
center of the octahedron. They are held together only at their
terminals by the comprehensive, triangular tension net. It is the
simplest form of tensegrity.
The 12-strut, 48 tendoned tensegrity cube, which is unstable.
