ORIGINAL: Twoshoes Really, only an abstract and infinitely small thing called a "point" at the centre wouldn't be turning. The hub would still be turning, because it's a physical object much bigger than a point. When people say hubs don't turn, they're making an approximation. *I even spelled it centre for you. Then again, you probably knew this all along and you're trying to trip me up to make me look foolish!!! Yeah, that point would be a limit, approaching but not quite zero. I think that's the point of the mental exercise. Especially since peon learned it in math class. But it does illustrate an element of power exchange. Part of the reason people crave it is because, in some situations, concentrating leverage increases force and 'work'. The hub of the wheel is constantly deciding for the rim what vector it's going, and the rim expresses that decision in ways that neither rim nor hub could do if they were squished into two separate piles of sawdust. But there are a lot of different ways to make a wheel... and sometimes the driving force is applied from rim centerwards, to the hub. Doesn't make the power less concentrated... And there's wheels where the spokes are turned, or the axle is hooked to a transmission and four other wheels, or... or... fuck it, this analogy has gotten out of babymommabangin' hand.
