The "k" is, in some sense, a measure of the average distance of the mass of an object from its axis of rotation. If all of the mass of the object is within radius r from the axis of rotation then the figure for k is guaranteed to be less than or equal to one.

The value of 1 is obtained when all of the mass is exactly at distance r from the axis of rotation. This would apply for something like a bicycle wheel where the mass is concentrated at the rim.

If you considered a thin square pipe rotating its long axis and if you measured its radius r from face to face (rather than from corner to corner) then I suppose that could give you a figure for k that is greater than one.
 
What does an object with k = 1 look like? What would it mean for k > 1?
