Every value links to the document that states it. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
Questions Is Drywall stronger than Iron? Iron is stronger: its yield strength is 186 MPa against tensile strength 1.5 MPa for Drywall (124x).
Which is stiffer, Drywall or Iron? Iron is stiffer: Young's modulus 207 GPa against 1.5 GPa for Drywall, so the same part in Iron deflects less under the same load.
Which expands less with temperature? Iron expands less: 13.7 µm/m·K against 16.7 µm/m·K for Drywall.
