A Moving Body on an Inclined Plane
Notes on load and motor, with a weighted lever diagram and a faint panorama
Two propositions consider a 'mobile' (moving body or load) on an inclined plane in relation to its 'motore' (the driving weight): the case when the load nearly equals its motor, and how the load grows lighter as the difference between its rising and the motor's descent increases. At upper right a small diagram shows a beam carrying two pulleys with a weight hung from it. A faint panoramic sketch, continued from folio 84r, spreads across the lower half of the leaf.

Load and motor on an inclined plane
Leonardo weighs the case of a moving body almost equal to its motor, favouring the object that rises less. He adds that a moving body becomes lighter the greater the difference between how much it rises and how much its motor descends. A beam with two pulleys and a hanging weight is drawn above the text.
Part of a panoramic sketch
Faint pen lines across the lower half of the leaf form part of a panoramic view continued from folio 84r, indicating low ridges and open ground. No transcribed text belongs to this sketch.
