See page Tensegrity Masts
This mast is composed of seven compression spirals and seven tension spirals. Half spiral clockwise the other half counter clockwise. It suggests the agility of a snake and the strength and flexibility of a giraffe’s neck.
Each vertebral body in a spine bears a formal resemblance to a stellated tetrahedron. It is possible to arrange a series of these stellated tetrahedrons as a tensegrity mast, such that the equivalent properties of load bearing combined with flexibility in rotation and bending is demonstrated.
