WebJan 3, 2024 · A real cause-and-effect relationship is given by an equation of the form. f ( t) = g ( t − Δ t) In this equation g is the cause and f is the effect and 0 < Δ t so that the cause always precedes the effect. In an expression like Hooke’s law both stress and strain are happening at the same time and causes happen before effects. WebSep 12, 2024 · Tensile strain is the measure of the deformation of an object under tensile stress and is defined as the fractional change of the object’s length when the object experiences tensile stress. tensile strain = ΔL L0. Compressive stress and strain are defined by the same formulas, Equations 12.4.5 and 12.4.6, respectively.

WebHooke’s law also referred to as the law of elasticity was discovered by an English scientist named Robert Hooke in the year 1660.
