urewe mean the force per unit of area, it follows that loadsplaced upon the two pistons, as in the diagram, will alwaysbalance one another, provided their masses are proportional to the areas of the pistons. Moreover, if the smaller piston be forced downwards through its cylinder, the larger piston… … THE PROPERTIES OF LIQUIDS 111 against the earths attractive force. Note that the lawof machines holds in this case. The work done by theone kilograin in falling one centimeter, for instance, wouldbe 980,000 ergs. The large piston with its load of 1,000,000kilograms would be lifted far enough to…
