Weights on cords, and the acceleration of falling bodies
From the suspended rod to degrees of velocity in free fall
The page closes the suspended-rod sequence and opens a new topic. First Leonardo states that the opposite weights a rod transfers to its two supporting cords stand in the same proportion as the spaces enclosed between the rod's centre and those cords, illustrated by a rod diagram marked 5 1/3 and 2 2/3. He then turns to falling bodies, noting that a thing moving by natural motion gains degrees of velocity at every degree of motion, with the last degree related to the second-last as the second is to the first. A vertical diagram lettered m, n, f, g, S accompanies the falling-body note.

Opposite weights proportional to the spaces on the rod
The spaces enclosed between the centre of the suspended rod's length and the two cords bear the same proportion as the opposite weights the rod gives to the cords that support it. The diagram is marked 5 1/3 and 2 2/3.
A falling body gains degrees of velocity in proportion
A thing that moves by natural motion acquires degrees of velocity at every degree of motion. These degrees stand in proportion, the last to the second-last, as the second stands to the first. The vertical figure is lettered m, n, f, g, S.
