no i don't think that there is a pot of gold at the end of the rain i think people just say that so that little kid try to get to the end of the rain bow but then get lost and no one can find them.so i'm pretty sure that they don't use simple mechines. i didn't really tell that there was a much of a relationship with input and output.
i learned the longer and skinier the wedge is the less force it needs. and the small and fatter the wedge is the more force it needs. so to day i have learn that the closer the fulcrum is to you the more force that needs to be exerted and the closer the fulcrum is to the object needs less force exerted on it.
