Added: October 31, 2008The strength of tree stems to resist bending in the wind is associated with the cross-sectional area of the stem. Strength is proportional to the diameter of the stem to the fourth power (DIAMETER). Small increases in diameter yield large increases in strength. This publication presents a theoretical examination of relative strengths of round stems as modeled by bending moments in solid cylinders. Resistance to torsional forces (twist) are two times that of bending forces.

Added: October 31, 2008Many of the models for determining loads and forces in tree structural systems depend upon crown shape. Tree crown shapes are integral to a variety of models because volume estimates, surface area estimates, or various types of two dimensional crown projections are directly related to crown shape. Calculating crown shape in a natural setting under dynamic loads requires continuous changes (over a variety of time and spacial scales) with growth, damage, and applied forces.
