Tensegrity, a portmanteau of "tensional integrity," is a structural principle based on the use of isolated components in compression inside a net of continuous tension, in such a way that the compressed members (usually bars or struts) do not touch each other and the prestressed tensioned members (usually cables or tendons) delineate the system spatially. ![[Pasted image 20241104235701.png]] Key points about tensegrity: 1. Tensegrity structures are composed of two types of elements: rigid struts (usually bars or rods) and tensile elements (usually cables or elastic tendons). 2. The rigid struts are not directly connected to each other; instead, they are suspended within the network of tensile elements. 3. The tensile elements are in a state of continuous tension, while the rigid struts are in discontinuous compression. 4. This arrangement allows tensegrity structures to maintain their shape and stability through the balance of tensional and compressive forces. 5. Tensegrity structures are known for their high strength-to-weight ratio, as they efficiently distribute forces across the entire structure. 6. The concept of tensegrity is found in nature, such as in the human body's musculoskeletal system, where bones act as the compressive elements and muscles, tendons, and ligaments provide the tensional forces. 7. Tensegrity principles have been applied in various fields, including architecture, engineering, robotics, and art. Some famous examples include the needle tower sculpture by Kenneth Snelson and the tensegrity-based robot designs by NASA.
