Example

Problem: A uniform bar has two small balls glued to its ends. The bar is 2.00 m long and has mass 6.00  kg , while the balls each have mass 0.300 kg and can be treated as point masses. Find the moment of inertia of this combination about an axis:a) perpendicular to the bar through its centerb) perpendicular to the bar through one of the ballsc) parallel to the bar through both ballsd) parallel to the bar and 0.500 m from it
