Method for determining strength of tree trunk

Abstract

A method for determining strength of a tree trunk includes connecting one end of a cable to an attachment point on the tree trunk above ground, with another end of the cable being connected through a strain gauge to a winch, wherein the winch applies a pulling force through the cable to the tree trunk until a deflection of the tree trunk meets a predefined deflection threshold. The method further includes measuring, using the strain gauge and a protector, a magnitude as well as application angle of the pulling force, respectively, and using the measured magnitude as well as application angle of the pulling force, based on a pre-established model that correlates a pulling force applied to the tree trunk with a displacement of the tree trunk, calculating a Modulus of Elasticity (MoE) of the tree trunk, that represents the strength of the tree trunk.
