it's about having two independent frames of reference
I know, but how
do you couple it ?
There are many ways, the two independant frames must be able to
interact.
From physic point the two frames are to close together, one is arranging the other.
A wheel in wheel construction will not work, even if you have two independent frames of reference.
So the two frames must allow also an sidewards movement.
What defines the reference frames is that motion - and work done - within them is measured in relation to them, as if they were stationary.
FoR's need to be masses. More to the point,
inertias.
As said, the output FoR is the KE FoR is the ground FoR. In any symmetrical (conservative) interaction, it would also be the FoR of the input energy / work / PE... but we don't
want a symmetrical interaction..
So we need the FoR of our input energy to somehow be accelerating around with the system, such that the input workload always begins each cycle in relative stasis, and thus starting out from the bottom of the
w² multiplier in the
½Iw² KE equation. This is why, in
any true PMM, everything must, of necessity, go around together; there can be nothing involved in it that remains stationary upon the axle. Emgat.
That Bessler was able to accurately friggin'
generalise the principles of mechanical OU decades before any of his contemporaries fully grasped the relationship between momentum and KE, CoM and CoE, gives the Lord's seal to his claims, and we should pay attention..
Statorless operation was neither a
prima facie nor
pro forma detail; it's the key to mechanical OU, because your input PE to the rotor is no longer bound to the ever-rising relative velocity of a stator, hence no longer
necessarily squares with rotor velocity '
w'.
Imagine you're riding a skateboard or roller-skates; whilst rolling forwards, you throw a heavy mass forwards - the counter-momentum decelerates you, and momentum and energy are conserved (PE=KE).
Now do that again, but without the recoil; now PE<KE. A superhuman throw!
Try another example - suppose you have a bat and ball, connected by string; if you could somehow hit the ball without incurring recoil, when the string goes taut the ball's momentum will be shared back with you and you'll start gaining forwards momentum, by the same increments each cycle, for doing the same amount of work each cycle - striking the same ball the same way with the same bat.. so your input work / energy is scaling linearly; simply summing. However the KE value of each of these little net accelerations of the system is
not accruing linearly; rather, it's
squaring with velocity... so even though you may only be gaining 1 mm/s in speed each cycle, the KE value of those 1 mm/s accelerations keeps climbing, for
ever, even though all you're spending is the constant per-cycle input energy times the number of elapsed cycles.
In a true PMM, the FoR of the input energy workload is accelerating with the system.
As such, it might be regarded as a 'divergent' inertial frame, since it's undergoing anomalous (unilateral) acceleration; any autonomously-accelerating FoR breaks energy symmetry with all other FoR's in the universe, ie. internally, if you've spent 10 J then you've achieved 10 J of work, but to any external observer you may have actually done much more or less (not 'appear to have done', since it's not an illusion).
What maintains CoE consistency between all 'normal' FoR's is CoM, courtesy of N3. N3 can't be beaten, 'because mass constancy'. But momentum gained from gravity and time circumvents N3 - we can gain angular momentum without torquing against a stator.
So the implicit objective - and the only kind of mech OU that can exist - is to fix the unit energy cost of momentum, so that its cost simply sums over successive cycles, while the system KE naturally squares up..
