Derived section properties

Integrated from a square-cornered outline: no root radius is published for this standard, and that is material a rolled section really has, so these run slightly below the published values. For L5X3-1/2X3/4 the computed area is 0.64% from published and Ix 0.13%. 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.
