each rotation.

Some of that circumference must rotate while it's off the ground.

The _radius_ at the bit on the ground is reduced, so it must spin
the tyre faster.

It would if a flat tyre was circular.

Since it isn't, you are talking relative ********

What is the radius of a tank track?

I'll take this slowly, but only once.

Imagine a wheel that was flat at the bottom so that it had half its
original radius. The rolling radius of the wheel is the radius where
it touches the ground - half the normal radius.

This bit at the bottom is the only bit that counts. The rest is not on
the road.

A tank track doesn't have a radius. It isn't a circle. The effective
rolling radius of tank wheels is exactly the same as it would be if
the track wasn't there - it's just they are rolling along a track, not
the road. This is why it is called a track laying vehicle.

The tank track (or any similar one) is in any case not relevant to this
discussion, as we are talking about a wheel and tire where the tire is
in contact with the whole rim of the wheel at all times.

Only a small part of a tank track is ever in contact with any of the
tank's wheels.

I introduced tehe idea of te tank track as an extreme example of a tread
that is much bigger than the wheels driving it, and rotates much much
slower.

It is the counter example - the case where the twits get it right, but
them you have to say what happens if te track IS rotating at the same
speed as the wheel driving it?

Because a tyre is a track/tread that *is* rotating at wheel speed. Even
thoiugh its a greater diamter than the wheel rim

The intention was to show that simple thinking leads to a paradox in
which the tyre is obviously rotating at the same speed as the wheel, and
yet their 'logic' says it must be rotating slower or the circumference
must somehow *contract* massively under load!

It's a fascinating example of scientific denial so to speak. Like
climate change they must 'save the theory' even when the data lead to
contradictory results.

Judging by here, its likely a technical problem that well over half the
population would get wrong...

Which also gives some degree of value to the false claim that '97% of
scientists say' meme.

And eplains wihy 47% of those with opinions voted to remain in the EU.

And a very high proportion of those with secondary education.

What we find is that undeducated people see things pretty much as they
are and dont pretend to understand them.

People with education who have been *told* how to use more copmplex
models *think they are smarter than they are*. It is in the end only a
small proportion of top brains that can actually think for themselves
that can puzzle it out and get to the right answer.

The rest might as well memorise te Koran by heart, because they never
will think independently. Radical Islam. Socialism. Climate change.
The EU. They will beleive in whatever they are told to believe by people
they consider to be their intellectual superiors - the authorities to
which they appeal.

That is why the remoaner class - funadmentally the over educated and
less intelligent middle class, are in fact the most gullible.

At the bottom the uneducated expect that people are talking **** to
them. They just dont believe anything except cash in hand and how much a
pint costs. At the very top people who can really think for themselves
understand much of what is going on, but are either not going to let on,
or are actively told to shut up.

Blairs triumph was to capture the imaginations of the over educated and
less intelligent middle class, increase their numbers by borrowing money
and giving it to them to go to 'uni' on the absurd proposition that
since people who were bright enough to get to university made more
money, sending people to university who were frankly thick as pig****
would in the end get them more salary.

The odd thing is how many believed him.

But since this little experiment, Perhaps its not so odd. Thats how self
important stupid people behave it seems.
