L6x6x3/4 — Dimensions and Section Properties

Dimensions and key properties

L6x6x3/4 drawn to the proportions tabulated below, with the axes at the centroid, x̄ = 1.77″ and ȳ = 1.77″. z is the principal axis of least radius of gyration, the one a compression check uses. The toe radii are not drawn.

Weight: = 28.7 lb/ft
A: = 8.46 in²
d: = 6 in
b: = 6 in
t: = 0.75 in
Ix: = 28.1 in⁴
Sx: = 6.64 in³
Zx: = 11.9 in³
rx: = 1.82 in
ry: = 1.82 in
rz: = 1.17 in
