L3x2x5/16 — Dimensions and Section Properties

Dimensions and key properties

L3x2x5/16 drawn to the proportions tabulated below, with the axes at the centroid, x̄ = 0.51″ and ȳ = 1.01″. z is the principal axis of least radius of gyration, the one a compression check uses. The toe radii are not drawn.

Weight: = 5 lb/ft
A: = 1.48 in²
d: = 3 in
b: = 2 in
t: = 0.313 in
Ix: = 1.32 in⁴
Sx: = 0.662 in³
Zx: = 1.19 in³
rx: = 0.945 in
ry: = 0.562 in
rz: = 0.428 in
