Given an independent variable x and a dependent variable y, y is directly proportional to x if there is a non-zero constant k such that The relation is often denoted using the symbols "∝" (not to be confused with the Greek letter alpha) or "~": or Given an independent variable x and a dependent variable y, y is directly proportional to x if there is a non-zero constant k such that The relation is often denoted using the symbols "∝" (not to be confused with the Greek letter alpha) or "~": or WebbStress is proportional to strain in the elastic region of the material's stress-strain curve (below the proportionality limit, where the curve is linear). Normal stress and strain are related by: σ = E ϵ where E is the elastic modulus of the material, σ is the normal stress, and ϵ is the normal strain. Shear stress and strain are related by:
