I'm studying elasticity right now in my chemistry class, and I'm confused as to what exactly tensile stress (and maybe compression stress too ) might mean. It's given in N/m^2. And you're stretching the material. Is the cypher I'm given indicative of what's happening only one side? Indicative of the pulling force acting on one edge of the material? Also, I'm curious as to why Young's modulus is independent of an objects dimensions? This is interesting because elasticity does depend on this kind of things (the object's dimensions).
