L3x2x3/8 — Dimensions and Section Properties

Dimensions and key properties

L3x2x3/8 drawn to the proportions tabulated below, with the axes at the centroid, x̄ = 0.54″ and ȳ = 1.03″. z is the principal axis of least radius of gyration, the one a compression check uses. The toe radii are not drawn.

Weight: = 5.9 lb/ft
A: = 1.75 in²
d: = 3 in
b: = 2 in
t: = 0.375 in
Ix: = 1.54 in⁴
Sx: = 0.779 in³
Zx: = 1.39 in³
rx: = 0.937 in
ry: = 0.555 in
rz: = 0.426 in
