Mechanics of Tensegrity Prisms
Tensegrity prisms are three-dimensional self-stressing cable systems with a relatively small number of disjoint compression members, invented by Buckminster Fuller. They form novel structural geometries and they constitute a class of mechanisms which have not been previously studied for possible application as variable geometry truss (VGT) manipulators. They have a number of seemingly advantage...
متن کاملOn tensegrity in cell mechanics.
All models are wrong, but some are useful. This famous saying mirrors the situation in cell mechanics as well. It looks like no particular model of the cell deformability can be unconditionally preferred over others and different models reveal different aspects of the mechanical behavior of living cells. The purpose of the present work is to discuss the so-called tensegrity models of the cell c...
متن کاملModels of cytoskeletal mechanics based on tensegrity
Cell shape is an important determinant of cell function and it provides a regulatory mechanism to the cell. The idea that cell contractile stress may determine cell shape stability came with the model that depicts the cell as tensed membrane that surrounds viscous cytoplasm. Ingber has further advanced this idea of the stabilizing role of the contractile stress. However, he has argued that tens...
متن کاملTensegrity: the architectural basis of cellular mechanotransduction.
Physical forces of gravity, hemodynamic stresses, and movement play a critical role in tissue development. Yet, little is known about how cells convert these mechanical signals into a chemical response. This review attempts to place the potential molecular mediators of mechanotransduction (e.g. stretch-sensitive ion channels, signaling molecules, cytoskeleton, integrins) within the context of t...
متن کاملA Primer on the Mechanics of Tensegrity Structures
We outline the formulation of the theory and the more fundamental results regarding the stability analysis of the class of tensegrity structures: structures which are composed of pin-connected inextensible cables and rigid bars.
