I found a link where I think the author must have been sitting at the end of the tequila line as he wrote it. Perhaps a version of this (or perversion I should say) is where people got to thinking about wheel nuts spinning "faster" than the wheel. If your wheel nut is tight it is impossible they can move at different angular velocities. How on earth anyone could have ever thought (or posted such a thing) I can not begin to understand. Those who are not in the business are, of course, forgiven. It is all too easy to believe the "experts." (Most politicians immediately come to mind here.) Also, just ask Jamo if you should accept MY legal advise!

Make sure you have a bottle of tequila beside you when you read this...I don't think there is any other way to understand it. It is good for laughs, if nothing else. You should NEVER believe hook, line, and sinker, ANYTHING that is written to the web by ANYONE...ME INCLUDED! (Come to think of it ESPECIALLY ME! ) Seriously, you should run your OWN thought experiment on EVERYTHING ANYONE posts or advises you (religion comes to mind here and so do lawyers--no offense Jamo, or my other esteemed lawyer buddies out there).

Here it is: I think you better sit down in a chair that is not too easy to fall out of while reading this one.

Now you know why I never trust Wikipedia. My brother always tells me it is a "distillation of the entire world's stupidity."

A-Snake,

As I mentioned in my above post, "Remember, an F1 car can decelerate at some 4 g's and they certainly can't accelerate at 4 g's so for the "Jamo empty bottle argument" F1 should make make the threads REVERSE of what they are on our cars... Alas, they don't."

I guess F1 cars now decel at 6 g's! That is AMAZING to me!

As for the rotational inertia of the spinners...the rotational energy of a rotating wing nut at 2000 rpms is basically nothing in comparison to a 22 ton (probably MORE, but I haven't had time to run the numbers--see there, don't believe ME either!) clamp load exerted by the threads on a properly tightened wing nut. Rotational inertia is so small in comparison at that point to the clamp load it is simply lost in the noise of the system.

Remember CLAMP holds the wheel on...not the thread direction.
