This page provides data for area, weight per unit length, moment of intertia, Section Modulus, Radius of Gyration and centroid location for "MC" channel members.
A dxf file with drawings of various MC sections ( MC .dxf) is available for download.
ws = weight per foot of steel sections, lb per foot A = area, in^2 I = moment of inertia, in^4 k = radius of gyration, in x = centroidal distance, in Z = section modulus, in^3 a b t A ws I1-1 k1-1 Z1-1 I2-2 k2-2 Z2-2 x -- ----- ----- ---- ----- ------ ----- ----- ---- ---- ---- ----- 4 2.500 1/2 4.0 13.8 8.9 1.48 4.4 2.2 0.7 1.3 .857 6 3.000 5/16 4.5 15.3 25.4 2.38 8.5 5.0 1.1 2.0 1.050 6 3.000 3/8 4.8 16.3 26.0 2.33 8.7 3.8 0.9 1.8 .927 6 3.000 5/16 4.4 15.1 25.0 2.37 8.3 3.5 0.9 1.8 .940 6 3.000 5/16 3.5 12.0 18.7 2.30 6.2 1.9 0.7 1.0 .704 7 3.625 1/2 6.7 22.7 47.5 2.67 13.6 7.3 1.1 2.9 1.040 7 3.500 3/8 5.6 19.1 43.2 2.77 12.3 6.1 1.0 2.6 1.080 7 3.000 3/8 5.2 17.6 37.6 2.70 10.8 4.0 0.9 1.9 .873 8 3.500 7/16 6.7 22.8 63.8 3.09 16.0 7.1 1.0 2.8 1.010 8 3.500 3/8 6.3 21.4 61.6 3.13 15.4 6.6 1.0 2.7 1.020 8 3.000 3/8 5.9 20.0 54.5 3.05 13.6 4.5 0.9 2.1 .840 8 3.000 3/8 5.5 18.7 52.5 3.09 13.1 4.2 0.9 2.1 .849 8 1.375 1/4 2.6 8.9 20.0 2.76 5.0 0.2 0.3 2.0 .270 8 1.250 3/16 2.2 7.6 17.8 2.83 4.5 0.2 0.3 0.2 .264 10 4.375 13/16 12.1 41.1 158.0 3.61 31.5 15.8 1.1 0.2 1.090 10 4.125 9/16 9.9 33.6 139.0 3.75 27.8 13.2 1.2 4.4 1.080 10 4.000 7/16 8.4 28.5 127.0 3.89 25.3 11.4 1.2 4.0 1.120 10 3.500 1/2 8.3 28.3 118.0 3.77 23.6 8.2 1.0 3.2 .933 10 3.375 3/8 7.3 24.9 110.0 3.87 22.0 7.3 1.0 3.0 .954 10 3.500 7/16 7.4 25.3 107.0 3.79 21.4 7.6 1.0 2.9 .918 10 3.500 5/16 6.4 21.9 98.5 3.91 19.7 6.7 1.0 2.7 .954 10 1.500 1/4 3.3 11.1 38.6 3.44 7.7 0.4 0.3 0.3 .284 10 1.500 3/16 2.8 9.4 34.4 3.53 6.9 0.3 0.4 0.3 .281 12 4.125 13/16 14.7 50.0 269.0 4.28 44.9 17.4 1.1 5.7 1.050 12 4.000 11/16 13.2 45.0 252.0 4.36 42.0 15.8 1.1 5.3 1.040 12 3.875 9/16 11.8 40.0 234.0 4.46 39.0 14.3 1.1 5.0 1.040 12 3.750 7/16 10.3 35.0 216.0 4.59 36.1 12.7 1.1 4.7 1.050 12 3.625 5/8 10.9 37.0 205.0 4.34 34.2 9.8 0.9 3.6 .866 12 3.500 1/2 9.7 32.9 191.0 4.44 31.8 8.9 1.0 3.4 .867 12 3.500 7/16 9.1 30.9 183.0 4.50 30.6 8.5 1.0 3.3 .873 13 4.375 13/16 14.7 50.0 314.0 4.62 48.4 16.5 1.1 4.8 .974 13 4.125 9/16 11.8 40.0 273.0 4.82 42.0 13.7 1.1 4.3 .963 13 4.125 7/16 10.3 35.0 252.0 4.95 38.8 12.3 1.1 4.0 .980 13 4.000 3/8 9.4 31.8 239.0 5.06 36.8 11.4 1.1 3.8 1.000 13 3.875 1/4 7.9 27.3 219.0 5.25 33.7 9.9 1.1 3.5 1.060 18 4.250 11/16 17.1 58.0 676.0 6.29 75.1 17.8 1.0 5.3 .862 18 4.125 5/8 15.3 51.9 627.0 6.41 69.7 16.4 1.0 5.1 .858 18 4.000 1/2 13.5 45.8 578.0 6.56 64.3 15.1 1.1 4.8 .866 18 4.000 7/16 12.6 42.7 554.0 6.64 61.6 14.4 1.1 4.7 .877 24 4.000 1/2 17.7 60.0 1340.0 8.72 112.0 19.5 1.1 6.2 .850 -- ----- ----- ---- ----- ------ ----- ----- ---- ---- ---- -----
