Leonardo da vinci engineering notebook

But the da vinci arts fair sketches beneath these ominous words were dismissed by the 1920s museum director as irrelevant notes and diagrams in red chalk.

The boat enters a lock of the canal, and the lower gate is closed.V A in London has one on permanent display that fits in the palm of an adult hand while others were on larger sheets that were bound or rebound after Leonardo's death.This water flow equalizes the pressure across the upper gate, thus allowing gate to be opened and the boat moves to the next lock.It is widely recognized that Leonardo had an exceptional grasp of friction centuries before the modern science of tribology was codified.As Watt struggled with inventing a working steam engine in the mid 18th century, he worked with complicated transmission systems because engineers feared that a simple crank-and-rod motion would not work with the irregular stroke of the steam piston.
