Tell us again how raising your centre of gravity doesn't
affect your stability of balance when cycling.

You're trying to tell us that is does.

Are you saying a raised centre of gravity when cycling has no
effect on stability?

It is up to the person that mentioned raised CoG to explain the
relevance.

Surely the laws of physics don't differ according to who is quoting
them? Nugent made a clear observation based on simple physics as
can be found in dozens of textbooks.

The raising of CoG?

You claim it is incorrect. Please show how it is incorrect.

I have made no claim about anything. Do you know what the word
'relevance' means?

Or were you trolling Nugent again?

You are putting demands on me, not Nugent. You are trolling me.


You replied to Nugent: " You're trying to tell us that is does".

Which is to say you disagree with him. If you actually meant you agree
with him them please say it now.

Be clear.

The horizontal shifting of the centre of gravity from a moving backpack
(and the rider's contortion to move the back pack into place) make for an
additional difficulties in maintaining stability -- on top of raised CoG.

I wonder why TSM320 is having such difficulty understanding school
physics.

Centre of gravity raised.

And?

Of course, science doesn't affect cyclists.

Proper science does. Nugent science doesn't.


Nugent cares little for the laws of Momentum (until he has to stop
unexpectedly, of course)

Childish.

Your lack of ability to argue on point speaks volumes about you.

Tell us again how raising your centre of gravity doesn't affect your
stability of balance when cycling.

Of course it does. Raising the centre of gravity of *anything* renders
it less stable than it would be with a lower centre of gravity.

Sigh.

Would it be just the same if a wardrobe were fastened to a roof rack
on an SUV?

No.

Do the laws of physics and gravity work differently for (a) bikes and
(b) everything else in the universe?

The laws of physics and gravity do not work differently for bicycles.
The knowledge of how it applies is called science.

Can you point out, in a clear scientific way, where you disagree with
Nugent's statement. I am always interested to learn if I have
misunderstood something.

The laws of physics and gravity do not work differently for bicycles.
The knowledge of how it applies is called science.

If the effective centre of gravity of a bicycle and its rider is raised,
eg, by placing a heavy load high up, perhaps by the wearing of a loaded
backpack, what effect does that have on its stability? Does it:

(a) decrease stability, or

(b) increase stability, or

(c) have no effect on stability?

Good. You don't disagree that raising the centre of gravity of a bicycle
and rider will have an adverse effect on the stability of the machine
and rider.

You are trolling. Goodbye.

You're doing is the equivalent of saying that the sun rises over one
horizon and sets over another. When asked why? you then ask "are you
claiming it doesn't do this?" when the answer you should be giving has
something to do with orbit and rotation.

You claim a). Now show your working.

There we have it.

You are insisting (with as much force as you dare for fear of rightful
ridicule) that raising a cyclist's centre of gravity will not decrease
that person's stability.

Thank you for being as clear as you feel able. It'll do. Your meaning is
plain enough.

Let's throw in the principle of moments.

There's another factor affecting roll from the near inevitable change in
handlebar direction while trying to restore the backpack to its original
position.

If TMS320 feels he lacks the ability to explain in mechanical terms why
all this makes no difference to stability, then perhaps TMS320 could get
on his bike and confirm it for himself.

On yer bike, TMS320!
