How Does a Tree Break?,y to prepare this material, and what a competitive disadvantage against the neighbouring tree, which boldly and somewhat light-heartedly grows up tall, dispensing with excessive safety, and leaving the heavyweight safety hypochondriac in the shadow of the dare-devil.

Shape Optimization by Growth in Engineering Design,at this model gets by using less fuel. As already mentioned, nature does not know this scruple. Some of the following examples are industrial commissions and have mostly been built and successfully tested.

It will reveal the history of this loss only to the practised eye, and as the years go by it becomes increasingly difficult to recognize and interpret the details of its body language (Fig. 127). However, the tree will never actively obliterate its history, as bone does.

The bending stresses on the trunk surface can be calculated from these distributions with Eq. (3), assuming a circular trunk cross-section. Now, assuming tha
