Tensegrity, a simple example, and uses in Industry

August 18, 2023

Tensegrity is a structural principle that combines tension and integrity, or as Buckminster Fuller, who coined the term, put it: “islands of compression in an ocean of tension”. Tensegrity structures are composed of isolated components under compression (such as rods or struts) that are held together by a network of continuous tension (such as cables…
