Distribution of a hung weight between two angled cords
Balance and pulley diagrams labelled with loads of 16, 8 and 4; lifting devices below
The sheet ranges over Leonardo's statics of suspended weights, with rows of small balances and pulley frames each labelled with the loads they carry (16, 8, 4, 12). A note states that when the cords m n and n f meet at n in a right angle, the two lateral weights are each double the central one. Lower on the page are working mechanisms - an inclined graduated bar and a crank-driven winch raising a bucket-shaped weight - marked only with numbers, without continuous prose.

Right-angle joint doubles the lateral weights
When the line m n and the line n f, touching at n, form a right angle, the two side weights are each double the weight hung at the middle. The rule governs how a central load is shared between two cords set at an angle.
Balances and pulley frames labelled with their loads
Several frames carry pairs and triples of weights over pulleys, marked 8 16 8, 16 16 16 and 4 16 12, illustrating how equal and unequal loads balance across a beam. The numbers record the load at each suspension point.
Inclined graduated bar and crank winch
At the foot of the sheet Leonardo draws a graduated inclined bar and a crank-driven winch lifting a bucket-shaped weight through a system of cords. No text accompanies these mechanism sketches beyond the numeric load labels.
