L3x3x3/16 — Dimensions and Section Properties

Dimensions and key properties

L3x3x3/16 drawn to the proportions tabulated below, with the axes at the centroid, x̄ = 0.81″ and ȳ = 0.81″. z is the principal axis of least radius of gyration, the one a compression check uses. The toe radii are not drawn.

Weight: = 3.71 lb/ft
A: = 1.09 in²
d: = 3 in
b: = 3 in
t: = 0.188 in
Ix: = 0.948 in⁴
Sx: = 0.433 in³
Zx: = 0.774 in³
rx: = 0.933 in
ry: = 0.933 in
rz: = 0.586 in
