• Label: Stem modulus of elasticity
• Entity URI: https://w3id.org/APD/traits/trait_0014018
• Type: numeric
• Definition: A stem [PO:0009047] physical quality [PATO:0002079] trait which is the stem's modulus of elasticity [SWEET:propPressure/ModulusOfElasticity], its resistance to being deformed [SWEET:phenSolid/Deform] elastically [PATO:0001031] (non-permanently) when a force [PATO:0001035] is applied. It is calculated as the ratio of the force applied to wood per unit area (stress) to the stem's deformation (bending).;A measure of stem stiffness and elasticity, which is how much the stem is deformed elastically (bends) under stress. It is calculated as the ratio of the force applied to stem per unit area (stress) to the stem's deformation (bending). This is the modulus of a compound tissue made up of bark and wood (or xylem) and potentially pith and could also be called structural modulus of elasticity. Trait is also called Young's modulus for a stem.
• Additional comments: None
