Dimensions
h = m, b = m
Area
A = h·b m2
Centroid
yc = b2 m
zc = h2 m
Perimeter
P = 2·(h + b) m
Second moments of area
Iy = b·h312 m4
Iz = b3·h12 m4
Polar moment of area
Ix = Iy + Iz m4
Radii of gyration
ry = IyA m
rz = IzA m
rx = IxA m
Torsional constant
It = 0.141·h4 m4
Torsional section modulus
Wt = 0.208·h3 m3
