Three rings (planar circles) are "linked" together, but you'll notice that none is directly linked with another.
- The red ring is "behind" the yellow.
- The yellow ring is "behind" the blue.
- The blue ring is "behind" the red.
Still, while none is intertwined with another, it is impossible to pull them apart.
Is this a paradox?
Can this really be built?
If the rings were oblong instead of circular, you could link them in
3-D so that each link (instead of ring) fits inside the next. Try
it with three paper clips.
There are some 3-D wood puzzles that look like the wood pieces are
linked, but of courseone of the wood pices slips, allowing the puzzle
to be taken apart/put together.
As far as the possibility of the linked rings (or linked links), it is
very possible to build such a thing, but it would have to be
manufactured in the linked state--you couldn't put solid, unlinked
rings in the configuration shown in the picture.
