Suspended beams under weights, tested by experiment
Three loaded horizontal beams and a small rod balancing 2 against 2, marked 'Tested'
Several suspended horizontal beams are sketched, each loaded with weights (pairs of 8 and 4 pounds above, and a heavier 64 / 4 / 77 case), with a small beam near the foot balancing 2 against 2. The single word written across the page, 'Tested,' marks these as results Leonardo verified by experiment rather than by calculation alone. The figures continue the notebook's study of how loads distribute between a beam's pivot and its arms. Faint numeric labels along the beams are not separately transcribed.

Loaded beams verified by experiment
Three horizontal rods hang from pivots, loaded by weights and by further rods, with values such as 4 and 8 and a heavier 64 / 4 / 77 arrangement. The note 'Tested' records that these load distributions were confirmed by experiment rather than reasoned alone.
Small rod balancing 2 against 2
A small suspended rod near the foot of the page carries equal weights of 2 on either side of its pivot, a minimal balanced case set beside the larger loaded beams above.
