The bottom line is it takes the same amount of work (energy) to move a 500 pound mass, all a lever does is make it possible for humans to do it without going to machinery. The lever doesn't make the impossible doable, it makes the impossible for the human machine with its power limitations doable, possible. Don't confuse the two. I can build a machine that does a certain amount of work over a short period of time with huge engines/ motors, or I can lever it and spread out the time it takes to do the work with a smaller engine, in most cases the time factor is acceptable. My car can easily go 500 miles no problem and it has a little over 200 HP, but I'm never going to win the Indy 500 with it, so they build an 800HP machine that can win it. The difference is time to "do" not "doability" (sic). Jim
