Systems allow changes in mechanical properties: organisms
Systems in nature allow organisms to change shape or their mechanical properties without changing the properties of given materials thanks to articulated struts.

Systems build around articulated struts combine nicely with muscles; sometimes, as in insect skeletons, the muscles are on the inside, but the principle is the same. Among the best features of these systems is their ability to alter shape or overall mechanical properties rapidly without having to change the properties of specific materials…But even tensile tissues other than muscle may sometimes change properties fairly quickly in response to some chemical signal. These alterations have been studied most extensively in the so-called catch connective tissue of echinoderms (Motokawa 1984; Wilkie 2002). A starfish undergoes an impressive mechanical transformation as it shifts from being limp enough to crawl with its tube feet on an irregular substratum to being stiff enough so the same tube feet have adequate anchorage when pulling open the shell of a clam."
