think about this.
I currently have an object that is 19' long and weighs 5000 lbs.
1) The center of gravity. for this load is is 9' back from front.
2) There is a pivot point 10' back from front. (axle)
a) This pivot point is 10% behind the center of gravity.
b)In Theory to lift the front of weight, since its 10% more weight forward on pivot location, it would take 500 lbs (10% of 5000 lbs) of force to lift it (tong weight)
4) now if I extended a leaver on front of this weight, out 5' (50% more), would it still take 500 lbs of force to lift the front of this weight, or 500 lbs - 50% leaver = 250 lbs?
I mean your fulcrum is still the axle, but we just added a longer leaver (hitch extension)
I don't think hitch length extension is multiplying weight, I think its reducing it?
but now if I put a 5' leaver out of back of truck, that is fixed to truck, with center of truck as axis,
and have a pivot point where it connects to the front of this 500 lb weigh, (like a truss or hitch extension) that will multiply the 500 lb weight that is on the pivot end
