I have enough technical knowledge to know it's not that simple. Why
are you so ready to suck up to Nugent when he never backs up his
claims?

Don't *you* support the thesis that a higher centre of gravity
reduces stability (ceteris paribus, of course)?


Sigh.

For a car or table that is stable when upright, yes, a lower CogG for
a given base allows it to tip to a greater angle before it falls over.
This is easy to calculate and demonstrate practically.

For a compound inverted pendulum (ie, a person on foot, running, on a
bike etc), it might, it might not. For the purposes of discussion we
can make it simpler and consider a simple inverted pendulum having a
point mass.

If not, why not?


You genuinely don't get it. You make a claim, it's your call.

OK, let's try to make it simpler for you. Which is likely to be better
- the rider down in a triathlon tuck or the rider on a sit up and beg?

You can even do your own experiment. Get a pen and balance it
vertically on your palm. Impossible, isn't it? Now get a broom and do
the same. Try it head up and head down. Which is easier?


That's fine and answer a question about your approach to this.


Typo.

That should have read: "That's fine and answers a question about your
approach to this."

Apologies.

There are only two possibilities.

1. You (correctly) do recognise that a raised centre of gravity reduces
stability but for reasons of your own, daren't admit it.

2. You (quite incorrectly) don't accept that a raised centre of gravity
reduces stability.

There are no other relevant possibilities.
