Question

A rectangle measures 30 cm by 50 cm. Point masses with mass 420 g are fitted at the four corners. Assume the connecting rods between the point masses have negligible mass. Find the moment of inertia of the system about an axis perpendicular to the rectangle plane and passes through i) one of the corners and ii) the center of the short edge (point p).
