Magilla, you gotta see this
So I'm watching team pursuits on the NBC site - you know, looking for
evidence of synchronicity - and I noticed something really interesting. You can actually *see* the change in wheel speed between the straights and the turns. How? In the video, the riders' wheels appear almost stationary at that speed, cause the position of the brand markings closely matches the sampling rate of the video recording - sometimes it even looks like the wheel is rotating slowly backward. It's this phenomenon he http://www.michaelbach.de/ot/mot_wagonWheel/index.html When these teams are riding the hamster wheel, you can actually see the change in wheel speed as the riders go in and out of the turns. Synchronicity was harder to determine. -rj |

But did they go faster or slower?! I can only say for sure that you can see a distinct shift. If the team's wheels appear stationary on the straights, they appear to be rotating slowly forward on the turns. If they appeared to be rotating slowly forward on the straights, they appear to rotate faster in the turns. And, if they appeared to be slowly rotating backwards on the straights, they shift to a stationary appearance in the turns. The fastest teams go at a speed (on the straights) that makes their wheels (with three markings) appears almost perfectly stationary. The GB team's wheels seemed to rotate forward very slowly on the straights. It's interesting, have a look: http://www.nbcolympics.com/video/pla...elcode=sportcy -rj |

Tthe spokes slow down to the point where they're stationary but the stickers are still moving around.
