Weightless Weight
« on: May 01, 2009, 11:27:44 PM »
Hello all, I have a book with 32 mechanisms for a single weight to apply its own weight into lifting itself upwards therefore becoming light... Each design is a result of hard study... I have just made one of them and it does some special things and I thought I could share this with you to see what you think...

Below is an equal seesaw that pivots on a stand.
A weight hangs on a piece of string which runs up and over a pulley attached to the right hand side of the seesaw, then running down to the pulley attached to the stand and then up to the left hand side of the seesaw to which the string is attached.

The weight aplies its weight to the right hand side of the seesaw and also gives an equal downward pull to the left hand side of the seesaw creating a balance with just one single weight!

If you push the left hand side of the seesaw down, it takes hardly any effort causing the weight to slowly rise, once you stop pushing down on the left hand side of the seesaw, the weight does not fall back down but retains its height at any point of the lift. Also, an interesting thing to note is that when the weight is slightly raised, its slightly easier to push the left hand side of the seesaw down (lifting the weight) than it is to push the right hand side of the seesaw down (lowering the weight)...

I made a picture...I like pictures   :P

From what Alexioco has said about this .... that regardless what load weight is used ...it will balance.  No matter if you use 1,10 or 100 kilos

the work to move the load up should very little and basically same for any weight.

Even when the load is off the device it is balanced and can return to a low position to pick more weight.

...now to go prove myself wrong :P

Hey, looks quite an interesting idea, few more things to note though, when the left side of the lever goes down and the right side goes up the string is being lowered but not as fast the the seesaw goes up therefore it lifts, but the weight does not lift very high, so you would nee a bigger seesaw to lift it that hight in ur pic

Quick update ....tried a basic set up...does not look good ...I'll explain in a bit
 :(

Ok a little more experimenting ...I did find a balance point. It was around 45 degrees from flat
I made a picture ( who would have guessed )

I feel the angle of the loads at each end of the seesaw make the difference in balancing

In the picture .... I show a fix ( not tried yet )  that might help....still  I think it will not balance flat

Hey Alex.   How many lbs. of weight would be required to lift
a 10lb. weight in your first drawing?  (Providing you set that weight on the top left side of the lever ).  Thanks.

This concept that Alex put forth is about balancing a load so that it takes very little energy to move the load up. 

think of a seesaw  with 100lb on each end-  "Balanced"..  add one pound  to one end and the other 100 lbs will move up.

Thanks Lilhawk,    But are you saying I will be able to lift a car with this set up with just a slight pull?

sorta if this proves out.   

depending on the range of the seesaw which will see unbalancing the further the angle of tilt.  So if the balance goes out by say 1%

that means a 3000 lbs(car) weight will need at least 30 lbs of force to stablize it. 10% difference in weight at the ends of seesaw with 3000 lbs

means you need at least 300lbs to lift.

Also to keep balance the seesaw tilt will probably have to be limited to which will make a lift stroke small depending on scale.

actually I should not talk ...I need to try that fix first..if that doesn't help...     I think this idea is mute

Ok I tried  that "fix" ....well before I had balance but at an useless angle...and the seesaw at a flat angle felt no resistance( way off balance)

now....I can't find a balance point but ..... I do feel a resistance throught out a decent range in the seesaw

Ok ...well this got me thinking ....one more "fix" to try before I give up on this...

Alexioco,

This is a very interesting lever-design...
What happens if we pull the string around the rim of a circle, instead of straight..???

Well, we will have a differens of approx. +/- 10 % to the opposite side !

The big question is: Will we still have balance?

wow wow wow hold your horses

Firstly let me say I have built this...

The seesaw balances even when its straight, you can even make it balance with the righthand side of the seesaw facing down (just slighty though) the weight makes itself light by appling its own weight to balance itself at any point of the lift so a light weight can lift a heavy weight.... This is just one of (32) of my drawn devices which I shall post over a period of time, they all have different ways of working, my latest design seems to be very promising, the weight should be able to lift itself without any help at all...

back to this one though, this design has alot of capablitlies which some are quite funny...

for example, if you had a large seesaw you could scale up a building by standing in a lift (you are the weight instead) and by jumping up, the mechanism would follow you up then when you land, you wont fall back down, you can also play on a seesaw without the need for somone the other side hahaha

Alex

What? Why hold?
Which design did you built, Alexioco?

The 'T' as you posted in your opening post or my latest 'Y-Lever Wheel' design proposal?

Anyway...try to SWING the weight...give it at slight push and see what happens! Amazing stuff...

Alex...please post something more than one design picture and saying this works...I like this idea so I tried  it and posted my results and my opinion why your design does not work.  I'm still working on this...trying different versions of your design.
