Q-

umm that whole lever thing doesn't work out exactly... because you can't forget that the amount of work done is given by force times distance.

Sooo to move a certain unit of weight (bat) with a force of half a unit, the distance from the fulcrum to the spot where force is applied must be twice the distance between the weight and the fulcrum.

For example, to cut in half the force required to move a weight resting 1 meter (about length of bat) from the fulcrum, we would need to apply force 2 meters from the other side of the fulcrum. How you gonna do that?

The amount of work done is always the same and independent of the dimensions of the lever (in an ideal lever).
