The shear modulus is one of several quantities for measuring the stiffness of materials. All of them arise in the generalized Hooke's law: • Young's modulus E describes the material's strain response to uniaxial stress in the direction of this stress (like pulling on the ends of a wire or putting a weight on top of a column, with the wire getting longer and the column losing height),
