Weightless Weight

[Lilhawk]

thanks Hans ...in your picture what angle did you start your seesaw at? if you have time I would be interested in seeing  results from steeper angles around 45 degrees.  Thats where I found a balance point with that design.

Has anyone really tried this? Here is a WM2D simulation that says it does not work.

Hans how can you say that it does not work? I have made the thing, you cannot campare reality with wm2d.... The weight balances and becomes light, commonsence tells you that when you look at how it works, the weight pulls one end down while at the same time resting its weight on the other end thefore its always balanced, I'm looking at my model right now, I now have it in my hand, ok now i have just put the sawsaw straight and im looking at it balanced, im now lifting it with hardly any force and every time I stop lifting, it does not fall back down...

@ Alexioco,

I don't know what you have built so I cannot comment on this. However I will state that the device as drawn cannot work. Common sense does not validate the idea. Do you seriously think we would build cranes the way we do if we could lift weights without effort in this manner?

Its just an idea I made that works, and I wanted to share it with you, nevermind...

Yes Lilhawk, you can find a point of equilibrium if the angle is steep enough. You can even get the side of the arm with the weight to go up, however you will notice that though the arm goes up, the weight actually goes down.
