The shear modulus of a material is always considerably smaller than the Young modulus for it. Whatdoes it signify?

The shear modulus of a material is always considerably smaller than the Young modulus for it. This signifies that the material is more resistant to changes in shape under tensile or compressive forces than it is to changes in shape under shear forces. In other words, the material is more likely to deform or break when subjected to shear stress compared to when it is subjected to tensile or compressive stress. The shear modulus measures the material's ability to resist shear deformation, while the Young modulus measures its ability to resist tensile or compressive deformation. Therefore, a smaller shear modulus indicates that the material is less resistant to shear deformation.
