Question 345444: why wont a 3 legged chair wobble but a 4 legged chair will?
Answer by Fombitz(32388)   (Show Source):
You can put this solution on YOUR website! Three points define a plane.
Once those three points are established adding another point, that isn't in the plane, would cause an unbalance, leading to the wobble.
If the 4th point is in the plane, then it wouldn't wobble either.
