Centre of gravity of a suspended weight
Balanced beams and counterweights, with the rule that a weight's centre of gravity falls below its support
A heading states the principle that the centre of gravity of any suspended weight will always fall below the centre of its support. Below it, red-chalk figures show rods and beams hung in various balanced arrangements, with hanging weights and a small circle. A note adds that the counterweight, through its cord, divides the beam at its midpoint.

Centre of gravity falls below the support
The stated rule is that the centre of gravity of any suspended heavy body always comes to rest below the centre of the point that supports it. This governs how each of the hanging assemblies settles.
Beams balanced by counterweights
The diagrams show rods and beams suspended and variously balanced, with weights hung from cords. The note explains that the counterweight, by its cord, divides the beam through its middle.
