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 Wood? Wood is stronger: its tensile strength is 99 MPa against 1.5 MPa for Drywall (66x).
Which is stiffer, Drywall or Wood? Wood is stiffer: Young's modulus 12.5 GPa against 1.5 GPa for Drywall, so the same part in Wood deflects less under the same load.
Which expands less with temperature? Wood expands less: 3.8 µm/m·K against 16.7 µm/m·K for Drywall.
