Without reading the engineering literature in its entirety, i can only guess it has to do with with deflection and is based on some sort of percentage of Deflection VS diameter. I.E. if a 2" shaft and a 4" shaft have an equal amount of deflection, obviously the 2" shaft has an amount of deflection that is a greater percentage of the diameter than the 4" shaft. And obviously the longer it is between centers, the greater the deflection will be.
