BIO325H5 Study Guide - Midterm Guide: Modulus Guitars, Tensile Testing
Document Summary
Young"s modulus is an index of how the solid materials of organism bodies go from compliance to stiffness. s. Young"s modulus (e) = an index of material stiffness vs compliance. Definitions by ennos: stress is the intensity of force or force per unit area [acting] on a material; units new tons per square metre (pa) usually given as kpaor mpaor even gpa. Strain is the relative deformation of a material under load; the change in length of the original structure: every material sits somewhere on a scale between stiffness and compliance, a scale of elasticity. The concept of the elastic conditions at a specified point inside a material is the concept of stress and strain. Numerically, the stress in any direction at a given point in a material is simply the force or load which happens to be acting in that direction at the point. (gordon chapt.
