A balance with two pivots, and studies of weights

A balance carried on two overloaded pivots

The two pivots are burdened with excess weight, yet in other respects the device is like a common balance. If one pound placed at d lifts six at f, then six at a lift one at c, and the whole comes into equilibrium.

Motion of the lettered arms a b, n, e, m

A lettered figure records the displacement of the linkage: if a b pulls by one braccio, that b comes to n, and e comes to m. The note ties the pull applied at one end to the travel of the marked points.

The two-pole balance instrument

A figure at the left margin is labelled a balance with two poles (pivots). It sets out the built form of the weighing device whose action the neighbouring text analyses.

A house with three terraces

Along the top edge of the sheet a small figure is labelled a house with three terraces. It is one of several stepped structures sketched at the head of the page.

A memorandum of birdseed

Down the right margin two labels read millet, and panic grass for the birds and likewise for the water. The jottings read as a household reminder set beside the mechanical figures.
