Resistance and freewheeling...

Stu Carter said:

*Could you get or make especially resistant bearings (ie. smooth but
resistant) for learning these skills, then go up to more free-running
ones once the basic skill has been acquired?*

This is an interesting concept but I believe all one needs to do is
select an appropriate grade on which to practice, rather than go through
the trouble of replacing their bearings. A slight uphill would have the
same effect as using "stunted" bearings on flat ground.

As to making the resistant bearings, I found salt water corrosion does a
good number on my skateboard wheel bearings... 🙂

Helloooo uber-geek! :p If that's truly the case then I can no longer
call myself a geek. It looks like, yet again, the bar has been raised.

Ok... a slight uphill gradient prevents forward motion, but doesn't hinder
backward motion - so surely the uni can fly out behind you easier. I can
see that the coast will be shorter and not gain speed (good thing!) as it
would if you were on a slight downhill, but I'm still not sure if it would
make things easier.

It's really not clear in my head... maybe I need to draw myself some
diagrams.

When I think about extreme cases of high and low rolling resistance, it
feels that my hypothesis is right, but how much effect would normal levels
of differing resistance have?

If the wheel isn't turning, then I can see that in extreme cases your
hypothesis is right. In that case your wheel is a solid (yet sort of
pivoting around the tyre contact patch) support. The resistance acts
one way or the other, depending on the direction of the force acting
on it.

But if, in spite of the high resistance, the wheel would be constantly
rolling in one direction, I don't think the high resistance would help
you. It would ensure a constant deceleration which you have to
counteract with going downhill (or by losing speed). But other than
that it would not provide any stability because the resistive force is
constant in direction. I think.

Simplistically, reducing your tire pressure slows the wheel down, and
can make quite a few things easier to do as a result. One pro
unicyclist uses about 35 psi for freestyle instead of the tire's stated
80 psi.

That would be the easiest and best method to introduce rolling
resistance in a controlled way.

If your amount of rolling resistance is constant, I don't see it
affecting your fore-aft balance. If you have input into it, such as in
gliding, this would of course be entirely different.

Only if you have a way lot of friction would you have something useable
to actually push against. In other words, the resistance of the bearings
gives "push back."

On a big wheeled unicycle, one of the reasons you can ride much farther
without a dismount is because pedal input not only moves the wheel in
the desired direction, the mass of the wheel allows you to push back
against it.

For example. Ride into a corner somewhere, with your pedals level. Now
if you press down on the front pedal, what happens? The cycle will lean
back. You can actually use this force to kind of shoot away from the
wall, if done right.

Oh, we can. We most certainly can.

Perhaps you meant to ask a different question.

P.S. On the subject of geekitude, has anyone else modified their
newsreader to replace tinyurls with the URIs the resolve to?

That's what I tried to explain too. And then there's the "if", because
the amount of rolling (or rotational) resistance may NOT be constant
but varies WITHOUT your input, such as from too tightly clamped
bearings that bind more at a specific part of the revolution. Then you
are WORSE off for coasting!

All in all I think: for coasting the lower the resistance is, the
better.

Disclaimer: I can't coast (on a uni).

I have. My username is kääpiövuohi.

However, I read a bunch of USENET groups, which is what I am looking at.
USENET. The fact there is an intermaweb forum gateway to it, doesn't
change the fact I'm looking at USENET.

So, I use my newsreader to read news.

Seems sensible to me 🙂

That may be because the newsgroup RSU is a text-only group and hence it
UPD'd on the attachment.

The solution is to either put the attachment somewhere on the www (or an
ftp server but that is less ideal) and then post the link on here, or to
post via the forum using the "Attach file" option.
