I belief it is something like this.

Hi Archer,
could you please explain your sketch drawing some more please ?

You have 2 dishes at the right side and 2 weights at the left side.
So is every weight at the left side 10.5 / 2 =  5.25 Kg each ?

Is the very right dish filled at the gound with water and then pulled
up via the 5.25 partial weight at the left side ?

Then the  very right dish moves it water at the top via
the tipping bar to the other left dish making this dish heavier than the combined 2 x 5.25 Kg=
10.5 Kg weight ?

Is the left dish then going down  on theright side and lifting the combined 10.5 kg weight
on the left side both up to the top ?

Or how should this all work ?

Many thanks.
Regards, Stefan.

I just measured in WM2D when the fulcrum lift-direction will change.

When the red weight is 2.0 Kg the  10.5 Kg yellow ball side will still go down.

When the red ball is 2.1 Kg the red ball side will go down and the 10.5 Kg yellow ball side will go up.

What do these catch hooks exactly connect together ?
The 2 weights or does the left leverarm connect once to the
left weight and once to the right weight
or once to both weights and once to only one weight  ?

And what how is the right dish pulled up via the pulley
4.5 Meters, when the left weight goes down only 90 cm ?
In this case the dish would be pulled up also only 90 cm....

Hmm...

And what does mean in Archer?s writing:


-        return cost = 4.55kg tested with pulley weight under beam


Where was this measured and where does this weight come from ?

Can somebody explain it in more detail please ?

Many thanks.
