On the heavy body.

c - b - a e d. The heavy body that does not weigh toward the center of the world always weighs in two or more places. It is proved: let the heavy body be a b c d, which does not weigh along the central line b e; therefore it weighs on the two supports b c and b d. Every heavy body weighs toward that aspect where it has the disposition to descend. This is proved by the demonstration of b a, which weighs at d, and b d weighs at a, because in such positions it has prepared the disposition of their descent. Conception. The heavy body that weighs upon two places does not have all its weight in one single place. The columnar heavy body placed obliquely divides its weight into 2 different parts, of which one weighs at its lower extremity and the other at the support that prevents its curved descent; therefore it does not weigh entirely toward the center of the world. This is proved by the penultimate. On the swinging weight.

The weight swinging from right to left and from left to right becomes the heavier at its appendage, or at the support of that appendage, the less oblique that appendage is.
