Let’s Talk About Material Stiffness and Why It Matters
When we talk about material stiffness, or the elastic modulus, as the science folks call it, we’re talking about how much a material squirms when we apply force. It’s a big deal in designing anything from bridges to bottle caps. The stiffer the material, the less it squirms under pressure.
But how do we measure this stiffness? And what makes one material stiffer than another? Let’s dive in and find out.
