PROBLEM 9.76 Using the parallel-axis theorem, determine the product of inertia of the area shown with respect to the centroidal x and y axes. SOLUTION Symmetry implies ( ) 1 0 xy I = Using Sample Problem 9.6 and Equation 9.20, note that the orientation of A 2 corresponds to a 90° rotation of the axes; thus () 22 2 1 72 xy I bh ′′ = Also, the orientation of A 3 corresponds to a 270° rotation of the axes; thus 3 1 72 I = Then 4 2 1 9 in. 6 in. 40.5 in 72 I == and 2 2 1 6 in., 2 in., 9 in. 6 in.
