Okay, I'll bite -- how do you get 7/6 to be anywhere close to SQRT(3)? 7/6 is
1.167, and SQRT(3) is 1.732. Is there an additional 2:3 ratio hidden inside the
"8880 transmission"?
Also, I'm having a little trouble figuring out how the transmission works in
the 8880. The instructions are here:
http://www.kl.net/scans/8000/8880/
and I've figured out that it has four wheel drive with three differentials, and
a mechanism for engaging one of four different output shafts to the input (or
the other way around, because you turn the wheels to make the pistons go) --
but it's still a little hard to see how it all fits together. It also looks
really spread out so I'm wondering if all that stuff is really part of the
transmission.
