Rotary moment of inertia
WebThe rotational inertia of an object is dependent on the mass the the arrangement of the mass within the object. A simple rule of thumb is- the more compact an object's mass, the less rotational inertia an object will have. We studied to shapes and their inertia. A ring and a disk. The rotational inertia of a ring with consistent density is ... 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 …
