One form of this law can be written using Lame coefficients and Kronecker's delta, and its anisotropic form can be expressed using Voigt notation.
One form of this law can be written using Lame coefficients and Kronecker's delta, and its anisotropic form can be expressed using Voigt notation. Cross-sectional area times Young's modulus divided by length is equal to the force constant of this law that was generalized by Cauchy to three dimensions. The tendency to return to an equilibrium position is the reason for the negative sign in this law that shows stress is directly proportional to strain.  Typically written as F equals negative k times x, for 10 points, identify this law used to calculate the restoring force on a spring.
