Also you've said it's not possible but you haven't explained at all why it isn't. Anyway i'd look up some of th!nk's old posts since he had a far better understanding than most (including me). Also fine rounded and not perfectly round (I thought this was obvious anyway because there aren't any plastics AR's that perfectly round)
I think I´ve made it pretty clear in my last post, but I´ll explain it once more and also with an illustration.
First of all: I´ve never said anything about perfectly round AR´s, so I´m not sure why you´re bringing that up. Anyways, here´s the physical explanation:
"Stealing spin" is basically transferring angular momentum from one beyblade to another. This is only possible, if at least one part of each bey can interlock with another. It doesn´t matter what part, it can be the base (if the WD or whatever isn´t too big), the AR or whatever. To a certain degree even the WD, but then it has no be not perfectly round. This is one example for how that transfer works and with that the literal meaning of LAD:
Picture 1: The zombie (beyblade 2) spins slower than the other one.
Picture 2: The attacking beyblade approaches and
picture 3: a protruding part of the attacking beyblade (let´s say a spike of the AR) hits the other beyblade at a protruding part of this one with force f, which is tangential to the the basically circular shape. Then you´ve got a lever arm l and the hit will transfer an angular momentum to the zombie of the magnitude delta m = f*l. Because of the conservation of momentum according to Newton the momentum the zombie gained is now subtracted from the attacking beyblade´s angular momentum (picture 4). Spin has been "stolen" or in plain words: One beyblade has pushed on the other sacrificing his own spin power.
If one beyblade is perfectly round (right picture), e.g. has a wide survivor, there´s just no radial perpendicular area the attacking beyblade could hit so that the force f is about tangential to the circle, or in other words, there is almost no lever arm to transfer momentum. The beyblade evades the attack so that it has (almost) no effect considering the momentum (spin) and is only pushed away, which makes it so perfect for survival, but technically not for a zombie.
Actually, this isn´t a matter of beyblade knowledge, but rather of physics (equilibrium of moments, collision theory, momentum transfer and momentum conservation). No matter how knowledgeable our bey hero was, even he can´t change physical laws. And if we had always stuck to what some great people once said just as a matter of principle and although it has already been disproved, science wouldn´t be where it is today.
