Derived section properties
Integrated from the section's own outline including the root and toe radii, whose arcs are integrated analytically rather than approximated by facets. For MT6.25X5.8 the computed area agrees with the published value to better than 0.01% and Ix to 0.06%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 25,744 mm³ |
| Elastic modulus, Sy | 7,082 mm³ |
| Plastic modulus, Zx | 46,812 mm³ |
| Plastic modulus, Zy | 11,239 mm³ |
| Radius of gyration, rx | 51.3 mm |
| Radius of gyration, ry | 16.9 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
