I think you have misunderstood what I like to show.Quote:
This construction will create an swinging with an increasing amplitude.
What Georg does not say, who pulls the rope?
I also asked myself this question, and the answer is the wheel, or rather the axis of the wheel, which is slightly offset as shown on the sketches of B.
This is the theory, currently I get a good oscillation, and I think I will soon get an amplification. :)
@Fletcher, I looked carefully at the MT44/48, or you have plans that I do not have, I only have the Wiki and it seems very complicated, good luck.
A++
There are 2 drawings on one page, on the left hand you have a weight on a rope and someone is pulling and releasing the rope.
So you will get an amplification because you do the action.
I think you have made such experiments already.
The second drawing is a drawing with 2 weights, one is arranging the other.
The construction itself is stable at the beginning.
The second weight is forming a bow, look closely.
When you now give the pendulum the first push, pull it will automatically increase its amplificarion. No further push/pull from you is necessary.
The second weight is doing your work at the right time.
Periodic force against periodic force with an offset of 180 degrees.
It will be easy for you to proof this.
