Scientific data represent Functional Measures of Technology from the developmental trajectory of three technologies: 1. for passenger aircraft: maximum sustained airspeed in miles per hour over 1932-1965 CE and 2014-2017 CE 2. for farm tractors: mechanical efficiency (ratio of drawbar horsepower to belt or power take-off –PTO- horsepower) over 1920-1968 CE 3. for freight locomotives: tractive effort in pounds over 1904-1967 CE
