Six suspended rods: a 'universal rule' of weights
A stepped table of load-splits, from 5 5/6 & 8 1/6 down to 0 & 4
Six diagrams of suspended rods, each ruled into equal divisions, present a stepped series of paired loads: 5 5/6 and 8 1/6 (against 7 and 7), 4 4/5 and 7 1/5 (6 and 6), 3 3/4 and 6 1/4 (5 and 5), 2 2/3 and 5 1/3 (4 and 4), 1 1/2 and 4 1/2 (3 and 3), and 0 and 4. Leonardo labels the pattern 'Regola universale' (universal rule), generalising how a load redistributes as its point of support moves.

Stepped series of load-splits across six rods
Six stacked rods carry paired weights that step through the series 5 5/6 & 8 1/6, 4 4/5 & 7 1/5, 3 3/4 & 6 1/4, 2 2/3 & 5 1/3, 1 1/2 & 4 1/2, and 0 & 4, showing how the share on each side changes as the support shifts along the beam.
'Regola universale' — a general rule of weight division
Leonardo captions the whole set 'Regola universale' (universal rule), presenting the numeric progression as a single general law for dividing a load between two points.
