L3x2-1/2x3/8 — Dimensions and Section Properties

Dimensions and key properties

L3x2-1/2x3/8 drawn to the proportions tabulated below, with the axes at the centroid, x̄ = 0.7″ and ȳ = 0.95″. z is the principal axis of least radius of gyration, the one a compression check uses. The toe radii are not drawn.

Weight: = 6.6 lb/ft
A: = 1.93 in²
d: = 3 in
b: = 2.5 in
t: = 0.375 in
Ix: = 1.65 in⁴
Sx: = 0.803 in³
Zx: = 1.45 in³
rx: = 0.924 in
ry: = 0.731 in
rz: = 0.517 in
