PROBLEM 9.193 Four 1 4 33 ×× -in. angles are welded to a rolled W section as shown. Determine the moments of inertia and the radii of gyration of the combined section with respect to its centroidal x and y axes. SOLUTION W section: 2 9.13 in A = 4 110 in x I = 4 37.1in y I = Angle: 2 1.44 in A = 4 1.24 in xy II == Note: total W angle 4 AAA =+ ( ) 2 9.13 4 1.44 in 2 14.89 in = Now ( ) ( ) angle W
