This swing bridge is fixed on to one of the banks with a vertical pivot that allows it to turn on itself. A system of ropes and pulleys help the bridge move in just a few minutes to make room for the ships or withdraw access across the water. The column acts as the balance point.
François I asked Leonardo da Vinci to work on a project which linked the Loire and Rhône rivers. The master conceived locks, river construction, swing bridges, and even paddle boats for the Kingdom's channels.
Its dual-level bridge offered separate passageways: one, the lower, was for goods, carts and horses.
The other, upper, was reserved for pedestrians.
The fighting vehicle is one of Leonardo da Vinci's most iconic machines. By combining the firepower of 30 canons, a command turret and a mechanized system for movement, it gave a new technological dimension to artillery on wheels which surpassed existing prototypes.
The level of precision of the model impressed: tortoise shell-like armor with thirty openings to fire on all sides, a turret offering a 360° view, an interior space that could accommodate a dozen men, and serrated wheels to ensure maximum support.
5 centuries later, it may have been an inspiration for our modern day tanks.
Since ancient times, mastering movement was achieved through a set of simple machines: the winch, lever, pulley, wedge, and screw.
Leonardo da Vinci became interested in the art of clock making, in particular in the springs used to create a continuous mechanism. The Florentine engineer was fascinated by springs: something which controlled movement in one dimension with unprecedented accuracy.
Studying movement allowed Leonardo da Vinci to innovate in the field of architecture. He came up with systems that distributed weight and force, such as the crane used in the construction of the dome of Florence cathedral, as designed by Filippo Brunelleschi.
A screw and wheel system which enables vertical and lateral movement of loads.
