Also, when talking about violation of CoE one should never forget that violation of CoE is inherently present in the very heart of theoretical physics -- the Hamilton's equations -- as I have already shown.

Now the fletchers of the world like to blabber about competence. However, when it comes to real arguments they are nowhere to be found.

Seriously omnibus - I know when you repeat what I've just said that you're rattled.

Are you embarrassed ? You should be ! - I'm embarrassed for you - You're giving moron's a bad name & soon they're gonna disown you !

-------------------------------------------

So ... Pe [mgh] = Ke

& Ke = 1/2 m v^2

Notice the element of velocity in Ke equation ?

So to help you with the answer - calculate the Pe loss.

Clue : that equals the Ke of the wheel after one cycle - work backwards to see if it matches the velocity you see & can measure  - sheesh, what an idiot !

P.S. don't confuse things with momentum !

Stop assaulting me undeservedly. Try to learn some physics first and then come here to do something more than blabbering.

What did you prove with these equations? Sheer nothing. Shall I call you a moron, then. No, because I'm a gentleman. I'll only ask you to learn physics before coming here and cluttering the thread with gibberish.

To be noticed once again. It is presumpuious to write Pe[mgh] = Ke because it goes against the experimentlal facts. Like I said, we see kinetic energy of two full rotations due to that small mgdeltaH. On the other hand, we see that the large mgH cannot bring about even one full rotation.

Slapping formuli frivolusly as fletcher does only serves to demonstrate his own incompetence and nothing else. If people such as fletcher want to prove their point of this device not being OU much much more is needed to be shown as a theoretical argument, not just slapping formuli frivolously.

I'll remind also, every time violation of CoE is discussed (independent of whether or not this particular case turns out to be OU in the end) that, contrary to what superficial people such as fletcher think, violation of CoE is inherently contained in the very heart of the standard theoretical physics -- the Hamilton's equations -- as I have already shown.

Oh, but you do deserve it omni_moron !

Learn some mechanics & how to analyse things properly before pushing your incessant rubbish !
