FIGURE 6

Mechanical parameters as functions of wood density for a constant biomass m in the stem cross section. (A) The Young modulus is computed according to the Eq. 6. (B) The stem diameter is computed according to Eq. 8 and (C) the stem flexural rigidity is computed according to Eqs 1, 6, and 8. (D) Maximum strain and (E) maximum stress are computed for the same fixed external load, respectively, according to Eqs 9 and 10.
