Name of person on a train during the 1940′s and 1950′s?
I need the name of the person who wrote main hydraulic equation on a train so he wouldn’t forget it. This main equation is used to derive equations for all of hydraulics
Uh, that’s kind of hard. You know trains were more popular back then, but the automobile was alreayd become popularized during th e1950′s with the construction of the interstate highway system.
