I didn't see mentioned the planimeter: "A planimeter, also known as a platometer, is a measuring instrument used to determine the area of an arbitrary two-dimensional shape." ~ https://en.wikipedia.org/wiki/Planimeter https://en.wikipedia.org/wiki/Planimeter
- perilunar 6y agoThat would be covered by the integraph category: > “The applications of the integraph are very numerous. With it we calculate areas, divide areas, determine centres of gravity, calculate moments of stability, load and resistance, solve algebraical equations, draw parabolas, etc.”
- carapace 6y agoHoly crap! Thanks! I missed that completely. (Too focused on the planimeter.)
