Don't know what you mean with the 12/6/8?
Sorry for the confusing notation, I should've written ~= meaning
approximately equal to.
30 cm ~= 12"
I wanted to say approximately equal so that people would understand
that for the following calculations I was using exactly 30 cm, which is
not exactly 12 inches. I only included the inches for the other
metric-system-challenged US citizens like myself -- I like to use the
metric system for math and such (typical in physics classes in the US),
because it is so much easier to work with, but when it comes to trying
to visualize the size, I find it very hard to use the metric system! So
I convert to feet and inches to help myself and others like myself see
the linkage in our mind's eye. (That explanation was probably much much
longer than necessary, I'm getting very very tired!)
Also, the idea of the virtual pivot moving to the side of the bike is
indeed confusing, and I really don't quite know what to make of it, but
I imagine it like this:
First, the virtual pivot is just the instantaneous pivot point, it is
always on the move, although the speed at which it moves will vary
(relative to the rotation/movement of the wheel). ... Uh. I forgot
where I was going with this, so I think it is truly time to sleep! Why
did I stay up until 11? I was going to go to bed after dinner...
