Answer. not by very much, if at all.

So the short answer to your question is "yes".

This seems to be a perpetual urban myth.

I just love watching Turnip arguing that a system that exists, is in
production and works is an "urban myth". What next, Flat Earth?


Oh dear. What I was arguing was that the reason the systemn works is not
what people here believe.

If you told me that essence of angel was what was in antibiotics and
they fought the demons in the pus, it doesnt mean that I disagree that
antibiotics cure infections, when I tell you you are talking ********.

But basic logic is another thing that has passed you by it seems.



Well you were the one to introduce circumference into this, a value
which is irrelevant to the relationship between the 2 things measured
(the vehicles speed and the angular velocity of the wheel) and what
relates them (the rolling radius).

The irrelevance of the circumference can be seen by looking at
caterpillar tracks. Ignoring slippage etc a 20m track goes round once
when the vehicle moves 20m. But that's true whether it is attached to
wheels with a radius of 0.5m or 0.25m. So the circumference tells you
nothing about the relationship between speed and the RPM of the wheels.
On the other hand, the (effective) radius of the wheels does.
