Er i didnt have a physics only course in middle school, i had science classes but they covered basic physics(including simple machines) along with other sciences. I had my first physics course in high school. I bought the thing, I can easily take measurements of the exact different lengths. I...

http://en.wikipedia.org/wiki/Mechanical_advantageI learned about that in middle school physics. I think i will ask in the mech engineering forum, I am thinking about doing some modifiications to the the crane anyways edit: I know how to calculate that for the boom, ratio of the distances to the...

Is this the right forum?
