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 HD 400 x 1086 the computed area agrees with the published value to 0.11% and Ix to 0.06%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
