L2-1/2x2x1/4 — Dimensions and Section Properties

Dimensions and key properties

L2-1/2x2x1/4 drawn to the proportions tabulated below, with the axes at the centroid, x̄ = 0.53″ and ȳ = 0.78″. z is the principal axis of least radius of gyration, the one a compression check uses. The toe radii are not drawn.

Weight: = 3.62 lb/ft
A: = 1.07 in²
d: = 2.5 in
b: = 2 in
t: = 0.25 in
Ix: = 0.656 in⁴
Sx: = 0.381 in³
Zx: = 0.688 in³
rx: = 0.782 in
ry: = 0.589 in
rz: = 0.423 in
