re: Weight rising in a flash...
raj,
You are on the right track. You are absolutely right about the spring(s) lifting the weight back up. But, you have to go to a slider or sliders, for it to work, two will do, (See agor95 sim).
The problem is; the sprigs have to shift, somehow----------

raj,
It helps to put numbers on things. Like so: Each weight 1.5 lbs, rod 1 lb. total weight of the slider 4 lbs. Stroke or displacement 2 inches,( 1 inch each way).
The force of the spring needs to be less than the weight of the slider, say 3 to 3.5 lbs. At 45 degrees past bottom dead center the slider forms a ramp with a MA of about 2 to one. So it only takes about half as much to lift it back up. Sense the force of the spring is 3 to 3.5 lbs it has no trouble lifting / resetting the slider by the time it rotates to horizontal.
Like I said; every half revolution the springs have to shift, somehow----------

Hey Bill .. I think that's the first time I've heard about the Bessler 'certain type of material' to construct any new machine quote. Either that or I'm getting really forgetful.ovyyus wrote:raj wrote:So anyone of you, please tell me how YOU think a weight could be lifted in a flash...Bessler wrote:We must bear in mind an important point. It is impossible to construct any new machine except by using a certain type of material.ovyyus wrote:Not relevant? Bessler might be suggesting that a 'certain type of material' makes it possible to lifts weights in a flash.
Can you give me the context for this Bessler quote, and any other information about it - thanx.

Fletcher,
I seem to remember vaguely something about a reference to some matter
" something that one can find in nature". I can't relocate it, sorry, I don't think he was refereing to a movement or principal but I may be wrong.
