SUMMARY
The moment of inertia for a uniform density rod bent into a square shape can be calculated using the mass M and length L of the rod, with the side length "a" defined as "L/4". The axis of rotation is at the center of the square. This discussion clarifies the relationship between the rod's dimensions and its moment of inertia, providing a foundational understanding for further calculations.
