Great man, it will be useful for our physics lab.

I tried to apply the Atwood Machine in the field at my job. I have to carry my 50 pound backpack up and down a 175' tower. So I thought to create an Atwood Machine using a 200' rope, two pulleys, my backpack(M1) and some weights(M2). The objective was to establish equilibrium so that I could easily take my backpack up and down the tower with little to no effort. My atwood machine failed miserably. I was able to raise my backpack (lowering the weights) with very little effort. But lowering my backpack (raising the weights) took a tremendous amount of effort - there had to have been at least 25lbs of resistance when lowering my backpack. I'm baffled in how it worked one way but not the other.
