The L 80 × 60 × 10 -mm structural angle has the following cross-sectional properties: I x = 0.808 × 10 6 mm 4 , I y = 0.388 × 10 6 mm 4 , and I 2 = 0.213 × 10 6 mm 4 , where I 2 is a principal centroidal moment of inertia. Assuming I x y is negative, compute (a) I 1 (the other principal centroidal moment of inertia); and (b) the principal directions.
