is to say, the rise in each one of the five is one- 

 fifth of the fall in A. And when the five barrels 

 are all combined in one, as at M, whose 

 total area equals theirs added together, then 

 again the weight is lifted at M one-fifth of 

 the distance through which the piston falls 

 at L.
