Play seesaw...
.....on net ( www.youtube.com ) ,then type on "search": "Seesaws on Potsdamer Platz,Berlin".
Have a nice time and...inspiration.

re: Play seesaw...
.....can be a simple childish game or even more.
Maybe,as Plato said "science is nothing but perception"...in the beginning.
So,take a short look at : www.youtube.com/watch?v=EgHngvugPSA
Emotion on a bigger and bigger seesaw,can turn back on itself and lead on to new thoughts...

.....this time,at Potsdamer Platz,in Berlin,if you take a short look at:

It''s a bigger seesaw...if you play a small seesaw,it can be not so much fun,but with one of this size ,you can be sure to have much more fan.
The entertainment can be a starting point for meditation:with the same "effort"(input),on an extended lever ,you have a "bigger trip"(output) between gravitational levels...
Sometimes the feelings of a simple game can help our thinking.

Let's say that the simplest expression of a gravity powered device,can be a "particular" seesaw ,with a "self-switching" unbalance (torque difference),on the same side of the fulcrum.

re: Play seesaw...
This is what I have been working on in the latest design I posted. Using two weights of five pounds each, one below the axle and one above, so that there is equal mass or weight on both sides of the wheel. When these two masses are allowed to slide up and down in a track and connected to each other, they can act as one end of a seesaw that will lift 10 pounds to a position above the axle, thereby overbalancing the wheel. (The two sliding weights remain on their own half of the wheel) If they are on the "longer side" of the seesaw, they can lift MORE than 10 pounds above the axle, so you have at least 15 pounds above, and only five pounds below, which is a significant imbalance. If this causes the wheel to rotate 180 degrees, the weights slide the opposite direction and the larger weight, which is now on the bottom, is lifted to the top and the process is repeated. I don't know if having an extra 10 or more pounds above the axle will cause the 180 degrees of rotation, but this is what I am working on and in the process of building right now.

re: Play seesaw...
.....but a big size one.
If you can't play in reality,try to think about that, on your "imaginary screen".
Remind that the "backbone" of mechanics ,and the seed of our science about this ,is the lever...

In a sense, Clock Makers employ the large "see-saws" if you will.
In Clock Building it would be referred to as a Flag or Flags...
essentially it allows a small wheel to give a much greater torque...this should work well with your trebuchet.

where man meets science and god meets man never the twain shall meet...till god and man and science sit at gods great judgement seat..a tribute to Bessler....kipling I think
re: Play seesaw...
Here is a Youtube video of what I am talking about. I would have two of these tracks on the wheel, one on each side of the axle so the wheel remains balanced. I could also put two on the back of the wheel, rotated 90 degrees from these two, just for fun.

re: Play seesaw...
I love the build!!!
Timber vs timber isn't the best for friction, but I guess you will be able to see why it does or doesn't work.
Looking forward to more.

re: Play seesaw...
I thought about using other stuff to eliminate friction, and decided that if it works, I'll build it out of GOLD! LOL. I wanted a little friction to keep it from dropping until the wheel gets it to the right place in the rotation. Even if it is close to working, I have so many different adjustments I can make that I could be on this one build for a really long time. Wood was the cheapest thing I could figure out to use.
re: Play seesaw...
I have a bunch of drawer slides with really nice bearings in them that I will use if this appears to be close to a working design. They will allow the weight to slide back and forth with little or no friction, since they are designed to hold 150 pounds. First I want to see if my design has the desired effect on the wheel. If it won't rotate, it won't do me any good to eliminate friction.

Then,think about the sensibility of an unbalance game (small "input") ,in the gravity field ,if you play a simple lever,but not a "wheel"(see "Wheel vs. lever..." topic...).
But,maybe for some people,a pleasant illusion is preferable to an obvious "empty" ,but so discrete reality.

re: Play seesaw...
iacob alex ,
From a previous post . from 1 - 4 the following on a gravity driven see saw , you have the beam at 30 deg in fig 1 with weights on left hand side , ob to the left , these weights is connected to 2 gears , inside a small housing , witch can pivot on the main beam . In fig one swing the 4 weights over to the right hand side , when the weights reach vertical position , fig 2 , start moving also the small housing , no back pressure in this position for the weights balance in this position , when moving the small housing the top weights will slow down causing the bottom weight to increase velocity , and come to rest as in fig 3 , now the weights is in rh side and ob on rh side .
See saw will end up as in fig 4 and ready to transfere the weights back to fig 1 . I call it Jacobs Ladder for the weights can be put together like a J L .
