I have read that Young's Modulus, like spring constant, is a measure of stiffness (how hard it is to deform a material). Though apparently, Young's Modulus is a way of doing so that applies only to the material and not its shape, where a spring constant value depends on the dimensions of the material. Is Young's Modulus meant to be the same as spring constant but for comparison of materials disregarding dimensions?
If this is true, then why is it that stress and strain incorporate cross-sectional area and length? If it has nothing to do with dimensions and only compares the materials' stiffness, why bring in those values?
Finally, I just want to confirm that spring constant doesn't literally apply only to springs, right? It does apply to any material with ductility/malleability, doesn't it?
