This page provides data for area, weight per unit length, moment of intertia, Section Modulus, Radius of Gyration and centroid location for unequal leg angle members.
wa = weight per foot of aluminum sections, lb ws = weight per foot of steel sections, lb A = area, in^2 I = moment of inertia, in^4 k = radius of gyration, in x and y = respective centroidal distances, in Z = section modulus, in^3 Size wa ws A I1-1 k1-1 Z1-1 y --------------- ---- ----- ---- ----- ---- ---- ---- 2 x 1-1/2 x 1/8 0.51 1.44 0.42 0.17 0.63 0.12 0.60 2 x 1-1/2 x 1/4 0.98 2.77 0.81 0.31 0.62 0.23 0.66 3 x 2 x 3/16 1.10 3.07 0.91 0.82 0.95 0.40 0.94 3 x 2-1/2 x 1/4 1.58 4.5 1.31 1.12 0.92 0.53 0.89 3 x 2-1/2 x 3/8 2.32 6.6 1.92 1.60 0.91 0.78 0.94 3 x 2-1/2 x 1/2 3.02 9.4 2.49 2.03 0.90 1.01 0.99 4 x 3 x 1/4 2.05 5.8 1.69 2.68 1.26 0.96 1.21 4 x 3 x 1/2 3.95 11.1 3.25 4.96 1.24 1.85 1.31 6 x 4 x 3/8 4.36 12.3 3.60 13.02 1.90 3.17 1.90 6 x 4 x 1/2 5.74 16.2 4.74 16.95 1.89 4.19 1.96 --------------- ---- ----- ---- ----- ---- ---- ----
