<s id="A18-1.25.02">For Archimedes has already adopted a reliable procedure on this part in his book with the title "Book of Supports".</s>
<s id="A18-1.25.03">We want to pass over of it what we need for other things and use of it now what refers to the amount of quantity, as is suitable for students.</s>
<s id="A18-1.25.04">The general point of view here is this: </s>
<s id="A18-1.25.05">If one has any number of pillars and crossbeams or a wall rests on them; further [if it rests] in the same or in a different position on the two outermost ones of them (the pillars), so that they extend beyond one of them or both at the same time, and if the distance between the pillars is equal or different, then we want to learn how much of the load affects each of the pillars.</s>
<s id="A18-1.25.06">An example for this is the following: If one has a long beam of even weight that is carried by men evenly distributed to the length and the ends of the beam, and one or both of the ends jut out, then we want to learn from each man, how much of the load comes to him; for the question is the same in both cases.</s>
