L10x10x7/8 — Dimensions and Section Properties

Dimensions and key properties

L10x10x7/8 drawn to the proportions tabulated below, with the axes at the centroid, x̄ = 2.8″ and ȳ = 2.8″. z is the principal axis of least radius of gyration, the one a compression check uses. The toe radii are not drawn.

Weight: = 56.9 lb/ft
A: = 16.8 in²
d: = 10 in
b: = 10 in
t: = 0.875 in
Ix: = 158 in⁴
Sx: = 21.9 in³
Zx: = 39.9 in³
rx: = 3.07 in
ry: = 3.07 in
rz: = 1.93 in
