More velodrome fun?

email hidden said:

Hi All,

Time for more Velodrome math.

I only just became aware that Chris Boardman no longer holds the hour
record.

I read that Sosenka used a 3.2kg wheel and 190mm cranks. The guy is 2m
tall so the long cranks isn't strange, but what about the heavy wheel?
Did that help? How?

Joseph

It helped only insofar as he mentally thought it would help, because
he believed the long-since disproven myth about flywheel affect and
heavy wheels. In reality it didn't matter one bit.

Faster through the turns.

The flywheel will smooth out changes in cadence.
Changing cadence is an energy drain.

Great. Now I have a comeback for the guy that says
that cadence is a red herring.

I don't think that works. I'm pretty sure the plan with the Hour Record
is to pick one and stick with it.

It doesn't matter which one,

You seem to be agreeing with me. ??

I have no idea about what I think about anything anymore. At the rate
I'm going, I'm going to start excusing Boonen's recent non-victory.

That's because you don't have any free will, and I'm not sure if you

You jest, but maybe it actually resisted acceleration in the turns,
and stockpiled a bit of energy there to be dispensed on the straights.

Yes, but did that impulse originate in your consious or unconsious, or
is that a rhetorical question when it involves a LIVEDRUNKard ?

If heavy wheels lowers the center of mass then it
increases the distance the CoM travels, decreasing
speed in the turns. Probably by a negligible amount.

And I have no intention of working out the geometry
to put numbers to that.

So maybe it does help by keeping the speed more constant by a
combination of increasing CoM distance traveled, and resisting
accelerating in turns.

Not significantly.

Ergo Magilla rides with a 3.2kg wheel.

You meant decreases.

Alright, I will play.

The relative amount of flywheel effect is as the
different in mass of the heavier and lighter
wheels to the overall mass. ~ 3 kg to 80 kg.

No, I meant increases. If the CoM is closer to the
track surface the radius the CoM travels through
the turn increases, the distance increases.

I'm thinking you are right. Else they could add lead to the bottom
bracket to get the same effect. Air drag is the main factor in the
hour record, so this must be about increasing thrust. If you've used
an exercycle with friction only vs one with a flywheel and friction,
the flywheel feels a lot more natural to pedal.

It's kind of a hybrid... I wouldn't have thought adding any weight
would help, but you can't argue with success. This is a closed course
and riding a steady speed is the objective, so once you've accelerated
that mass it will help you maintain a steady speed.
