MC7x19.1 — Dimensions and Section Properties

Dimensions and key properties

MC7x19.1 drawn to the proportions tabulated below, with the y axis at the centroid, x̄ = 1.08″ from the back. The inner flange faces are drawn at the standard 1:6 slope, which is not exact for every size. The flange toe radius is not drawn.

Weight: = 19.1 lb/ft
A: = 5.61 in²
d: = 7 in
bf: = 3.45 in
Ix: = 43.1 in⁴
Sx: = 12.3 in³
Zx: = 14.5 in³
rx: = 2.77 in
ry: = 1.04 in
