Determine the moment of inertia about an axis perpendicular to the page and passing through the pin at O. The thin plate has a hole in its center. Its thickness is 0.05 m, and the material has a density of 50 kg/m^3. (The pin is located at the corner of the 1.4 m x 1.4 m plate, the circle hole in the center has a radius of 0.15 m.)
