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 Steel? Steel is stronger: its yield strength is 385 MPa against tensile strength 1.5 MPa for Drywall (257x).
Which is stiffer, Drywall or Steel? Steel is stiffer: Young's modulus 200 GPa against 1.5 GPa for Drywall, so the same part in Steel deflects less under the same load.
Which expands less with temperature? Steel expands less: 12 µm/m·K against 16.7 µm/m·K for Drywall.
