Curved Motion's Release Point; Dart-Throwing with a Rod
Where a curving motion lets go its load; three figures of a dart cast from a stick
A measurement note places something 'through the middle of the bridge, opposite Scipione' at 28 1/2 once. The central question asks in what part of its curved motion the moving cause will release the body it carries. Three sketches show a dart launched from a rod in three positions, with a reminder to speak with Pietro Monti about these ways of throwing darts.

Release point of a curved motion
Leonardo asks in what part of its curved motion the moving cause will release the thing moved, that is the mobile — a question about where along a curved path a projectile is let go.
Three positions of a dart cast from a rod
Three sketches of angled rods show a dart launched from a stick in three successive positions, illustrating the throwing action studied in the motion question above.
Speak with Pietro Monti
A memorandum reminds Leonardo to speak with Pietro Monti about these particular ways of throwing darts.
