I've never really had a clear understanding of how mechanical computing worked, until today when I watched these US Navy training films from 1953.
Part 1 focuses on shafts, gears, cams and differentials.
Part 2 explains mechanical component solvers, integrators and multipliers. More information about ship gun fire-control systems
here.

Complete simple tasks that people do better than computers. And, get paid for it. In 1769, Hungarian nobleman Wolfgang von Kempelen astonished Europe by building a mechanical chess-playing automaton that defeated nearly every opponent it faced. A life-sized wooden mannequin, adorned with a fur-trimmed robe and a turban, Kempelen’s "Turk" was seated behind a cabinet and toured Europe confounding such brilliant challengers as Benjamin Franklin and Napoleon Bonaparte. Excuse me? Ah, yes. The
Mechanical Turk, by Amazon.
