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 H 300x150x6.5x9 the computed area agrees with the published value to better than 0.01% and I_x to 0.01%. Where a value is also published, the published one above is the one to quote.

Property	Value
Elastic modulus, Z_x	480,618 mm³
Elastic modulus, Z_y	67,671 mm³
Plastic modulus, Z_px	542,110 mm³
Plastic modulus, Z_py	105,121 mm³
Radius of gyration, rx	124.1 mm
Radius of gyration, ry	32.9 mm

Z is the elastic modulus and Z_p the plastic modulus, following Japanese practice.
