Determine the principal moments of inertia and the orientation of the principal axes of inertia (angle measured counter-clockwise from x-axis) for the cross-sectional area shown. The moment of inertia Ix, Iy, and the product of inertia Ixy are:

Ix = 10228.5 mm4 Iy = 1307.34 mm4 Ixy = -2880 mm4

Answer: ?max=11077.73mm4,?max=?163.58o,?min=458.41mm4,?min=?73.58o
