On one hand I wouldn't expect gyroscopic effects to be sufficient to be noticible, since the rate of revolution is so slow. On the other hand, I have noticed when accelerating while cornering rapidly that my car leans to the outside and to the front -- the front outside wheel is really pressing down vigorously. Since this is only noticible while accelerating it doesn't seem obviously gyroscopic, but since acceleration normally tends to make the car shift to the back, rather than the front, it is curious. Anybody know more about the mechanics of this situation? -- "Hypocrisy is the vasoline of social intercourse." (Who said that?)
