Roll on the 20th June

Hi All
As I have already pointed out but some don't listen this 20 to 1 is a illution because your not taking the beam weight into account and this is proven by exxc0mmon's video, the ruler drops on the long end lifting the short end before any weight is on it, if theres no weight where is the weight comming from to have it drop at the long end well the ruler ofcause the long ends weight is more then the short end hence the long end dropping, to get it level you have to put weight on the short end in this case 16 magnets I think he put before the ruler was level I could be wrong in that number but thats not important, now everything is balanced were no end has a greater weight then the other and you put one weight on ever side and it will drop to that side why because one side is unbalanced your not lifting anything so because your putting 16 weights on the short side your not lifting them 16 weight your just balanceing the lever as a whole, again the 20 to 1 is an illution if you have a balanced beam so both sides are lifted everything is even and you put 20ks on one side that side will drop then put 1k on the other nothing will happen if the 20ks lifted in this setup then you will be lifting 20 to 1 but it wont move and will never move.

ARCHERS complete point was that the extra falling weight on the one unit side[the weight of the lever itself] would give more work out with just one unit in adding the two falling together and doing more work by gravity in less distance Chet

you're getting closer.....   


What he said was that the momentum of the weight on te long end in "free-fall" provided more than enough energy to lift the lever, the +20kg, and itself back up to the top (though the mechanism for that last part is still unknown).

We watched the first two take place in his videos. the 3rd is suspected to come from the energy in the impact/'bounce' + the 20kg, in "free-fall" from its lifted location. This will have to include a method for detaching the weights from the lever at certain points during it's cycle.

at least thats the way i interpreted what Archer said about the subject...

Graham do you know where the threshold for OU is on a 5-1 balanced lever as I asked above   Chet

@ramset

For a perfectly balanced lever, where the weight of each end of the lever has no impact impact on the lifting of the weights, any lift ratio greater than the length ratio is overunity.

So for a balanced 5:1 lever, a lift ratio of 5:00001:1 would be overunity.
