12.3 Stress, Strain, and Elastic Modulus University

For a small stress, the relation between stress and strain is linear. The elastic modulus is the proportionality constant in this linear relation. Tensile (or compressive) strain is the response of an object or medium to tensile (or compressive) stress. Here, the elastic modulus is called Youngs modulus. 12.4:Stress, Strain, and Elastic Modulus (Part 1 As we can see from dimensional analysis of this relation, the elastic modulus has the same physical unit as stress because strain is dimensionless. We can also see from Equation \ref{12.33} that when an object is characterized by a large value of elastic modulus, the effect of stress is small.
