Balanced bars, added sums, and a court-hall measurement
Weight studies with a column of addends and a note on the size of the court hall
The sheet mixes several quick studies of a horizontal bar held in equilibrium, its ends and hooks marked with small weights (1 1 and 4 4), drawn over a faint red-chalk graduated scale at the left. A column of numbers in the right margin adds 28, 21 and 7 to a total of 56, and three small indeterminate sketches carry the note "30 – nothing empty." An inverted line at the foot records that the court hall is 128 paces long and 27 braccia wide.

Horizontal bar in equilibrium with paired weights
A horizontal bar is shown balanced, its suspension points and ends tagged with small loads written as 1 1 and 4 4, and again as 1 3/4 1/16. A faint red-chalk vertical scale beside it appears to serve as a graduated reference for the divisions of the bar.
Column of addends totalling 56
A short addition is set out in the right margin: 28, 21 and 7 are stacked as addends whose total is given as 56. The figures accompany the weight sketches rather than any money reckoning.
Dimensions of the court hall
A note written upside down at the foot of the page records the size of a room: "128 paces is the court hall, 27 braccia wide." It reads as a jotted measurement of an existing space rather than a design.
