Derived section properties
Integrated from a square-cornered outline — the fillet radii this family really has are not drawn, so the computed values differ slightly from published. For 2L10X10X7/8 the computed area is 0.41% from published and Ix 1.46%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 732,021 mm³ |
| Elastic modulus, Sy | 962,371 mm³ |
| Plastic modulus, Zx | 1,318,629 mm³ |
| Plastic modulus, Zy | 1,547,982 mm³ |
| Radius of gyration, rx | 78.6 mm |
| Radius of gyration, ry | 106.4 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
