For what I think I know, the mechanical advantage of a lever comes in exchange for the distance the load travels upwards, independent from the type of lever (I think).
So, let's say, in a (class-1) lever with a long area where the load is applied, but the effort is also applied in an even longer area. Is there a way of "shortening" it while maintaining the mechanical advantage?
I thought of putting a lot of small levers in sequence (with different lengths to compensate for the increase of force), one applying effort until the total of levers would make the same amount of force as the long single lever.
Let's say, someone then would organise them in a spiral, so they occupy less space.
Would that even be possible, or it is just a nonsensical question?
By the way, the intention with this question is to lift around 200 kg with the force of a leg.
