33" versus 36" Wheelsets....

Nope, one dime. Because think about it, the wheels don't deform THAT much when they contact the rail, which means that, essentially, the wheels are touching the rail at a single point.

In order for each wheel to have a dime sized contact point, they'd have to flatten out quite a bit.

I've heard its a dime per wheel. But anyways, here's the formula to figure it out...

The last time I saw this topic catch fire on the A-board, it seemed that no two people could agree on the benefits of the FVM wheels.  A while ago I converted about two dozen cars to test it out.  I found that they did roll better, added some nice low weight to the cars, looked far better, and gave off that pleasing clickety-clack.  Once things have turned around financially, I'll be adding FVMs to the rest of my cars.  I figure could outfit the rest of my modest fleet for less than the cost of a pair of Kato diesels.

They smell better too.  ;D Or is it that anything on the WP smells better?

Or you could just wake up and realize that the static frictional force does not depend upon surface area...

That response makes me all warm and fuzzy inside.   :

My head hurts looking at that, and I'm supposed to be good at those kind of things...

Now, why, would I want to do that?

You don't, as doing so oversimplifies the problem and doesn't account for rolling resistance and creep.

And those affect TE how?
