Davis and mott equation
WebFeb 21, 2024 · Basically, the Davis Equation is a resistance formula mainly used in basic go-stop situations like trains. The basic formula: R ′ = 1.3 + 29 w + .045 v + .0005 a v 2 w n R being resistance, w is axle load in short tons, n is the number of axles, and a is the frontal area of the train in sq. feet.
