re: BW in no gravity

Well, another dud. I ran all the numbers the right way and the internal negative torque from levers equalled the positive COM torque.

Lessons learned, at least.

re: BW in no gravity

YAY! I found the error in my torque calculations. I have to rerun the numbers.

re: BW in no gravity

Hey WaltzCee, My thought process is this: There are two categories of torque for this application: 1. torque generated by levers based on their own frames of reference. (for example: the wheel is fixed and the levers which are supposed to be free to move are only geared to each other.) 2. torque gen...

re: BW in no gravity

This has lever pairs geared together on each arm. outer weight is drawn as round and inner as square. they are same weight and lever length. they only change in gear ratio as shown in the drawing. connections aren't shown and timing mechanisms aren't shown. Parts can overlap. I'll walk through. (Obs...

re: BW in no gravity

Hi everybody, It's been a while so I'm not caught up on all the discussions. For two reasons, I wanted to contribute to the idea of no gravity. First, I always thought it wasn't really necessary in its natural form. Specifically you could just have a big spinning room with all your bessler wheels in...

re: On Gravity

Hi Silver Tiger, Man, that's a lot to think about. It reminds me of Bose Einstein Condensates and how they change behavior based on their low state of KE. I don't know much about their state of gravity but I would predict they would have different gravitational interaction than hotter masses at a ce...

re: Design Based on the Uphill Roller

Hello All, It's been a while for me. After thinking about the uphill roller, I dug around to see if it had been mulled over. Sadly I could find very little. If anyone knows of more, point me in the right direction. I agree. It will definitely try to settle at some elevation at some off-center locati...

Measuring CoM

Thanks Fletcher, Hmm, if I can sum all the y positions of all the weights that would help, but I don't know if knowing the moments will help on this design. The CoM will lower if my gear ratios are wrong but that is not what is supposed to "drive" the wheel. It has continuous torque in one...

Help with CoM in WM2D, anyone?

Fletcher, Thanks for the WM2D help so far! Is there any way to measure the system center of mass as a numerical readout on the Y axis? This would help me more than just watching the CoM symbol. So far in my models, it looks like my system CoM is somewhat stable as the weights revolve but I can't tel...

Ok Fletcher, I can see the system center of mass now. It is dropping more and more as the wheel turns. Bummer. This could mean the wheel has the wrong gear ratio, or the build is simply too crude(true), or the concept can't work, or any combination of those. Time will tell. I tried making a single c...

Thanks Fletcher! I will definitely try those tips. I did try view>system center of mass but I didn’t see anything. I will try zooming in. Do I need to have any objects selected to view center of mass? I was thinking of building chains out of very small circles and strings to wrap around the inner ...

Explanation of picture

Fellow Orffyreans, My apologies for poor photo quality. This is a similar setup as the original drawing in this Topic. There is an inner wheel geared to an outer drum so that: 1. The inner wheel moves faster than the outer in either direction and at an exact ratio. 2. Driving force (gravity) is appl...

re: Creating Infinite Distance inside a wheel

These wheels are otherwise identical but with the inner wheel on the left screen is positioned closer to the “dead� string which has no weight. This enables it to generate positive net torque. The concentric wheel on the right screen has a balanced net torque. I know it’s crude but I think it ...

re: One way wheel

Hi JGarriga, Nice drawing. I think it would stall out when a load or friction is applied. The test for me would be to rotate it 22.5 degrees ccw, halfway through a period, stop it, then let it go again. It would just be balanced at that point with nothing to start it up again. IMO there needs to be ...
