Centres of gravity of weights hung from cords
Statics of a beam and its suspended loads, with numerical division
Leonardo announces that 'the centres of the weights' are to be demonstrated below, and folio 206v is filled with numerous beam-and-weight diagrams marked with numbers. On folio 203r he explains that to know the loads carried by the cords supporting a weighted beam one must know either the spacing of the cords or the true number of the weights. A labelled figure states that the centres of the weights a and b are equidistant from the cord c.

The centres of the weights demonstrated
A heading announces that the following figures show the centres of the weights, introducing the many beam-and-weight diagrams that cover folio 206v.
Loads carried by the supporting cords
To find the quantities of weight that the cords sustain, where the beam bearing the weights hangs from those cords, one must know either the character of the spaces between the cords or the true number of the weights.
Centres a, b equidistant from cord c
A labelled beam figure states that the centres of the weights a and b are equidistant from the cord c, the condition under which the two cords carry equal loads.
