Dear Cupcakes,
the spot question probably such indeterminate structure and hinge frame, the centroid of the hinge should be the 1st to have, before that must determine the area (width x height), the area should compromise the whole area of the structure,
the x and y bar, is equal to the submission of Ax over the A, for the Y bar is vice versa.
Ixx=bh3/12 + A(y-y^)2
Iyy=b3h/12 + A(x-x^)2
Ixy=A1x1y1.........
