Wording it for you, desribing the artistic picture: << There are 4
rings one inside the other, each of which can rotate relative to the
next outer ring along diametrical axes. Initially all rings are in a
plane. Each ring can rotate with a time period T (360 days), when all
the others are frozen without any self driven motion. After what time
will all rings be in a plane again when driven independently? >>

Is that your problem? If so,it needs to be been set up as a problem
from mechanics/dynamics before getting into a mathematical solution. I
mean involving directions and speeds/accelerations if any.

(Taurus is a bull. Even a flimsy ring, need not be toroidal, may do
for your problem.)
