Well i really dont think that theres a pot of gold at the end of the rainbow. So I dont think that lepricons used simple machines either. So yesterday i really did'nt notice much about how input and output where effected.
Today though i noticed the the greater length of the wedge the less force need. The smaller the wedge is in length more foce is needed. With the lever I noticed that the closer the stone is to the object your trying to move the less force needed. However when the stone is further away from the object your trying to lift more force is needed to lift the object. Which makes moving the object pretty hard.
