Ok, still having problems here... Still trying to find out how much polycarbonate will bend. (and copper, for that matter!)

I found a lot of material data sheets, that have a reference to a "Flexural Modulus", as per ASTM D790 testing methodology, measured in Kg/cm^2. I have no idea what the result means!

Does anyone know what it means?
