[alfa] Unsprung weight

[alfacybersite <acs@xxxxxxxxxxxxxxxxx>]

I've been using the term for ages, but have no idea what it really 
means. I always assumed it simply meant a combination of all the items 
on the suspension, wheel / tire, brakes, etc. But if that was the case, 
it would simply be called suspension weight or something such as that.

What got me thinking about this was a 64 pound package which just 
arrived via the man in brown from IAP. Four red springs and four red 
shock absorbers. Even dividing by four, I'm thinking that is a lot of 
"unsprung" weight. Thinking further it occurs to me the spring is 
pushing upward. Does that add or subtract to the equation? Then there 
are the shock absorbers...

Don't get too technical, I'm not a racer guy and this is merely a 
curiosity + I'm sort of laying low since the Sheriff's helicopter flew 
over while I was primering late last evening. Then later a small plane 
flew directly over my, unh, err, exterior spray booth, at a pretty low 
altitude. Big Brother or merely paranoia? Only time will tell.
