L2-1/2x2-1/2x1/4 — Dimensions and Section Properties

Dimensions and key properties

L2-1/2x2-1/2x1/4 drawn to the proportions tabulated below, with the axes at the centroid, x̄ = 0.71″ and ȳ = 0.71″. z is the principal axis of least radius of gyration, the one a compression check uses. The toe radii are not drawn.

Weight: = 4.1 lb/ft
A: = 1.19 in²
d: = 2.5 in
b: = 2.5 in
t: = 0.25 in
Ix: = 0.692 in⁴
Sx: = 0.387 in³
Zx: = 0.695 in³
rx: = 0.764 in
ry: = 0.764 in
rz: = 0.482 in
