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 125 x 125 x 10 EA the computed area agrees with the published value to 0.20% and Ix to 0.04%. Where a value is also published, the published one above is the one to quote.

Z is the elastic modulus and S the plastic modulus, following AS 4100. Under AISC 360 the letters are reversed — S is elastic and Z is plastic.
