Hinged arm across a graduated arc, with a small figure
A graduated semicircle crossed by inclined arms, a graduated triangle, and a small pen sketch of a standing man
A faint graduated semicircle is crossed by straight arms or levers set at different inclinations, with a hinged jointed arm dropping across it and a graduated right triangle marked off along one side at the right. A small pen sketch of a standing man holding a long staff or rod appears at the upper left beside a few lines of Leonardo's mirror-writing. The figures continue the study of weights and arms measured against an arc; the text at the top and the faded writing at the lower left are not transcribed here.

Inclined arms measured against a graduated arc
A graduated semicircle is crossed by straight and jointed arms set at varying angles, while a graduated right triangle is scaled off along its edge at the right. The construction reads the inclination of an arm or the fall of a weight against the divisions of the arc.
Small standing man with a staff
At the upper left a quick pen sketch shows a standing man in profile, apparently holding a long staff or rod out before him. The little figure sits beside the written lines at the head of the page.
