L2-1/2x2x5/16 — Dimensions and Section Properties

Dimensions and key properties

L2-1/2x2x5/16 drawn to the proportions tabulated below, with the axes at the centroid, x̄ = 0.56″ and ȳ = 0.8″. z is the principal axis of least radius of gyration, the one a compression check uses. The toe radii are not drawn.

Weight: = 4.5 lb/ft
A: = 1.32 in²
d: = 2.5 in
b: = 2 in
t: = 0.313 in
Ix: = 0.79 in⁴
Sx: = 0.465 in³
Zx: = 0.839 in³
rx: = 0.774 in
ry: = 0.581 in
rz: = 0.42 in
