Two connected weights falling onto a crossbeam
Dropping two equal weights tied to one cord over a transverse beam
Two diagrams show a pair of weights, drawn as small circles joined by cords, coming to rest across an obstacle. The upper figure lays out the three points n, o, m of the connected weights; the lower figure shows the cord draped over a bar so the two loads hang to either side. Leonardo's note frames the study as the case of letting two equal weights, tied to the same cord, fall upon a beam set crosswise.

Two equal weights dropped over a crossbeam
The note describes letting two equal weights, tied to a single cord, fall upon a beam laid crosswise. As the cord catches over the beam, the two loads distribute themselves to either side, the case the figures analyse.
Connected weights at rest (n, o, m)
The upper figure lays out the linked weights as circles along a cord, marked n, o and m. It fixes the starting arrangement before the pair falls onto the obstacle.
