Grooved Axles

Good grief, guys.

"The force of friction is not related to area."
"WTF?! Are you saying that, mathematically, grooved axles being faster is a lie?? Without grooves, more of the axle would touch the wheel, which is more friction. The grooved axle in the picture clearly shows less contact with the axle which is less friction.You don't race here! You 'think' you're smart."

All that was said was that having less surface area does not mean less friction based on that alone. More area just means less pressure per sq. mm, but the overall amount of friction is essentially the same. And then it was said further that that isn't the whole of the effect when it comes to the axles. That some imperfections were removed from consideration (like a scratch in the bore from inserting a bent axle), and that there's conjecture about what else there is about the groove that makes it faster (refer to 5Kids' post on stability for the wheel).

There's been all sorts of reading into the original statement, all sorts of hackles raised, insinuations made, and calling out done all based upon things that were never said. /images/boards/smilies/rolleyes.gif

May I point out the statement that sparked this firestorm, and highlight two key words?
Mathematically, they shouldn't reduce friction, since surface area contact isn't a factor in that equation. However, since they reduce the actual area of contact...

There was never a claim made that the current best-practices aren't fast.

Now let's all get back to wringing our hands nervously in anticipation for Saturday's ICE #3. Or is it just me doing that?

No MEEE TOOO. My fast car either slowed down or the re-prep on 3 others made up some good time. This is really the first time I got in some track time. Hopefully I can get a good time deviation between my track and the NPWDRL. /images/boards/smilies/smile.gif Also have 2 scout cars in District this Saturday.
 
Just caught this thread and a little late to the party.

The groove provides "breathing" room and prevents "suction" due to the seal created from the oil.

Just tossing out ideas that haven't been touched upon yet. Any merit? No clue!

I'll do this before anyone else does.

Bottom line, grooved axles are faster.
