Why it's here
HN treats it as the classic demonstration of how analog mechanical computation works, especially the differential gear section.
What it covers
A 1953 US Navy training film on the basic mechanisms in fire control computers: shafts, gears, cams and differentials. It shows how these mechanical parts compute ship and target firing solutions.
