Plate of beam, winch and pulley figures
Numbered statics diagrams (26-32) with winch, pulley and coil sketches, labels only
Folio 169v is a plate of small mechanical figures, numbered 26 to 32 and carrying only letter-and-number labels rather than continuous prose. Tick-marked beams with letter labels such as a b c, q p r, n m o and c a b d continue the study of loads shared between supports, while sketches of pulleys with hanging weights, cranked drums and a spiral coil illustrate the lifting devices analysed on the neighbouring folios. The span figures, for example 4 16 and 10 10, match the load calculations of the surrounding pages.

Numbered beam-and-weight diagrams 26-32
A series of small statics figures, each labelled with a number (26 through 32) and with span figures such as 4 16 and letter labels a b c, q p r, n m o and c a b d, continuing the study of loads shared between two supports.
Winch, pulley and coil sketches
Alongside the labelled beams the sheet carries mechanical sketches, including pulleys with hanging weights, cranked drums and a spiral coil, illustrating the lifting devices analysed on the neighbouring folios.
