Center of mass vs center of rotation

WebSep 12, 2024 · In the case with the axis at the end of the barbell—passing through one of the masses—the moment of inertia is. I2 = m(0)2 + m(2R)2 = 4mR2. From this result, we can conclude that it is twice as hard to rotate the barbell about the end than about its center.
