SUMMARY
The discussion focuses on calculating the strength-to-weight ratio and modulus-to-weight ratio for a material with a tensile strength (σ) of 230 MPa, a modulus (E) of 15 GPa, and a density (ρ) of 1.85 g/cm³. The calculations yield a strength-to-weight ratio of 124,324.32 N/m²/kg and a modulus-to-weight ratio of 8,108,108.108 N/m²/kg. The participants clarify that the resulting units are indeed not dimensionless, as they depend on the chosen density units, either mass density or weight density.
