Sure you can. Spin it at 100 RPM, or 1000, RPM or even 25000 RPM... :)
Interesting conversation. I tend to agree the earth is not a classic
harmonic oscillator. Energy is not exchanged between different storage
mechanisms. It's rotational period has no natural harmonic frequency.
i.e. rotational period could be anything.
However I also agree it exhibits characteristics of other items that Q
can be calculated for. Rate of slowing, loss of energy per cycle, etc.
And since the definition of Q is varied and used quite widely, it seems
Q is also appropriate here.
Maybe Earth is a special case since after all it DID give us the second,
and we DO set our atomic clocks to IT every 6 to 12 months...

toying with us now...
