The Nature of Divided Weights
Weights shared between cord and prop (a pair of 4, and 8 with 4); lines a-n and m-f converge
A short heading announces that the page treats the nature of divided weights. The drawings show weights held partly by a cord and partly by a supporting stick: a pair each marked 4, and a skewed pair marked 8 and 4, together with three pairs of horizontal cylinders sharing a common axis. Leonardo asserts that the lines a-n and m-f both aim toward the center of the motion, meeting there at the angle of the pyramid they begin, and that whatever two joined weights do, many together, or a single weight of any size, will do the same.

Divided weights act like a single weight
This deals with the nature of divided weights. Whatever two joined weights will do, the same will many together do, or one only of varying sizes.
Lines a-n and m-f aim at the center of motion
The lines a n and m f direct themselves toward the center of the motion, and there they make the angle of their begun pyramid.
Weights shared by cord and prop (4, 8)
Two spheres each marked 4 stand side by side: one is held by a cord that begins at n and passes up over a, the other is propped by a stick. A leftward pair marked 8 and 4 hangs askew, its cord and stick off the vertical, and three pairs of horizontal cylinders share a common axis, one pair marked 4 and 8 with the vertical labeled m and f.
