Spring Coupling

[ARMCORTEX]

Since the subject was brought up.

Heres of Bobby's latest machine, can anyone guess its internal assembly ?

Think logically..

He calls it "Latest double action mechanical space energy harvesting machine all rights reserved by galaxel ltd"

BA loves to make curious machines that shake and rattle furiously.  All that shaking makes it difficult to take clean direct torque and speed measurements at sufficient bandwidth, but it can be done.  The other option of course is to attempt to self-loop.

He who guesses this device will understand a very very good design for implementing springy energy resonance.

Probably the best springy device ever made.

I will not respond to this thread anymore.

The concept does not work.  Springs don't make free energy.  The only energy that you can get at the output of a spring is energy that you transfer directly through it plus energy that the spring releases as it relaxes or less the energy that goes into the spring as it is tensed.  In a dynamic situation where the spring tenses and relaxes: the average energy added and subtracted by those two actions average to zero.  That means that your equations are wrong as the proof in my previous post showed, and your concept does not work.  The spring like any other coupling simply transfers the torque less losses between the two flange plates.  Contrary to your claims:  T_GENERATOR is on average always less  than T_MOTOR.  The average rotational velocities are the same.  P_{AVERAGE GENERATOR IN} < P_{AVERAGE MOTOR OUT}.

Do you mean say that  concept  of mechanical  advantage  itself is wrong?   Then  why do you use  pulley  or gear  arrangements  to  switch  between  speed  and  torque?    What  happens  if   smaller  pulley / gear   rotates  a bigger pulley /  gear  with same speed?   (if  mechanical advantage  is not  lost)
I  know  very  well  that  storing  and  releasing  energy  in a spring  will  not yield any  excess energy.   But   I am  not  using  stored  energy.    Working  principle here  is based  on  mechanical advantage.

These are very basic concepts that you can check out for yourself:

The product of force and distance moved on one side of a lever is, absent losses, the same as the product of force and distance on the other side of a lever. 

Coupling through different size pulleys, gears, etc, is just a rotary version of a lever.

I have already proven mathematically that your concept does not work as you claim.
