I think the "problema" of MT026 shows that all these motions for "weight C" need to move efficiently on a direct downwards slope by "slider E:", and/or need to be helped by an indirect downwards slope "angle A-C-E", and/or needs to be helped by a helper "weight B". All this while it needs to be two-way restricted by something like "rope D".Fletcher wrote:I believe the weight-wheels in 26 are the game changing hint of 26 i.e. use of rolling cylindrical weights as part of the 'apparatus' for continuous 'wheel' imbalance, in the presence of a separate Prime Mover 'arrangement'. Imo the hint is very obscure and well removed from the true purpose (not even remotely as shown imo) of rolling weights inside his wheels. So far removed that it is unlikely that anybody would ever stumble upon how they were actually used from this drawing alone, unless you had made other critical connections in MT, to join the dots so to speak.
The weight-wheels are replaced in 27 by heart shaped weights, not for functionality, but to reinforce how good a choice they would be, imo.
Because rolling downwards on a slope is difficult to make efficient (friction, noise, expensive metal, inertia of a rolling weight, and the need for a smaller low-friction axle to connect "rod B-C") we can actually just eliminate that slope in its entirety by making "path A-C" a floating transition: and so MT027 is born.. I think.
I see those cylindrical weights could have been grabbed from the nearest pendulum clock. But we don't know, so we can calculate.Fletcher wrote:In regards to the shape, size, and mass of the weights, we know they were cylindrical (no argument).
It seems to me that the dimensions are hard to obscure by a handkerchief cover once you can already determine that it is a cylindrical shape.
The least known fact are the sides.
When a weight is placed in the cups of two hands then it should be larger then two farmer hands for not being able to reach the sides, yet likely (not necessarily of course) smaller than the width of the wheel (11 inch, minus the width of the side boards)1715 - Christiaan Wolff wrote: He did not disguise the fact that the mechanism is moved by weights. Several such weights, wrapped in his handkerchief, he let us weigh in our hands to estimate their weight. They were judged to be about four pounds each, and their shape was definitely cylindrical.
So here my guess (metrics system) for a "4 pound cylinder". Talking about deciphering the translations: 4 pfund = 2 kg, or 4 pound = 1.81..kg
Say it is 25 cm long.
With 11.3 gram per cm³ I calculate a solid lead 2 kg cylinder to have a diameter of just 3 cm
When it's a hollow cylinder having an outer diameter of about 7.09 cm, then it would be 1/3rd cm thick.
And we can go on and on when we consider that a hollow lead cylinder would be structurally better when filled this with sand or wooden struts/discs and also adds to that weight.
As such I think this is yet another incomplete clue.
