Stress-Controlled Strength Distribution,Troll (1959) and other authors discuss the resemblance between wood and reinforced concrete. Figure 86 shows the underlying principle. Whereas reinforcing steel and cellulose are characterized by high tensile strength, concrete and lignin resist compression but cannot bear much tension.

It seems as if Kubler and Mattheck wanted to trick us into believing that trees only live and react following mechanical rules and strategies. To tell the truth, that was what I first suspected the aut

As a function of frequency, the power absorbed is a very characteristic ., or ., with a maximum at the frequency of the undamped oscillator. We shall finally l
