The main point in Professor Adams' paper, that strikes the practical designer is that the calculations are made with such exactness. Practical design is at best only an approximation, as the quality of material and the actual dimensions obtained in the shop vary in different machines. An important example of this is the dimensions of the air-gap in an induction motor. With the small air-gaps required in such machines, a variation of 25% among a number of machines sent through the shop at the same time, is not by any means uncommon.
