the stability of larger vehicles is all about dynamics. low COG is all
well and good at low speeds, but at high speeds its exactly wrong.

bogosity meter alert!




Agreed! Terry, where did you come up with that?

...Jim Thompson

from a book on gyrodynamics. and some browsing on gyrocars.

actually, isnt it kinda obvious? think about the forces involved when you turn a corner. now turn said corner at speed. the faster you go, the wider and lower your vehicle needs to be to maintain stability.

whereas with a bike, the faster you go the more stable it becomes - until, of course, tank-slapping sets in ;)

Terry


But you said "COG"!

As for the bicycle... think about it. Go really fast, then try to
turn ;-)

...Jim Thompson

bicycle? how quaint. 1000cc bicycle....professional riders go round corners PDQ.

I have seen a video of a bicycle with a small motor running a flywheel in the opposite direction; precession then works in the opposite direction - lean left to turn right. it was a pretty funny video.

Cheers
