Answer:

The moment of inertia about a "fixed" axis is unique.

The moment of inertia of a square is different for an axis that passes perpendicular to the center of the square as opposed to an axis that lies in the plane of the square.

Torque = I * alpha shows that angular acceleration depends on I but not on the angle thru which I rotates α = ω / t
