Bony Frameworks and Tree Frameworks Compared

The frameworks illustrated in Fig. 138 show trabecular bone (Fig. 138A) and the welded framework of an aerial-rooter (Fig. 138B) from which the host tree has fallen away or rotted. The two components are pleasantly similar in conception, and both certainly satisfy the axiom of uniform stress for their loading. The fact that they have arisen in different ways is unimportant, but the question of what distinguishes the adaptive potential of their design with a possible change of shape must certainly be discussed in this book.
