APFIVE Rotational Inertia and Axis Location
A system consists of two point masses m₁ and m₂ connected by a massless rod. If the rotational inertia about an axis perpendicular to the rod is measured to be 25% greater than the minimum possible value, what can be concluded about the axis location?
A
The axis is displaced from the center of mass
B
The axis must be perpendicular to the line joining the masses
C
The axis must pass through one of the masses
D
The axis is exactly at the midpoint of the rod
