WebSep 12, 2024 · Young’s modulus Y is the elastic modulus when deformation is caused by either tensile or compressive stress, and is defined by Equation 12.4.4. Dividing this equation by tensile strain, we obtain the expression for Young’s modulus: Y = tensile stress tensile strain = F ⊥ A ΔL L0 = F ⊥ A = L0 ΔL. WebThe elasticity coefficient is a numerical measure of the degree of variation in one variable (dependent) in response to 1% changes in another variable (independent variable). The coefficient indicates the percentage shift in the quantity demanded caused by a 1% change in price. The elasticity coefficient is expressed as follows: ‘E = (%∆y ...
