Unlike the concentrated winding, not every tooth pole is wound in a distributed winding; instead, coils are in slots and span multiple pole teeth. Since the winding may block slots from further insertion of wire, it may be necessary to wind a complete phase winding at one time. Comparison of concentrated and distributed windings
In power engineering, winding factor provides a way to compare of the effectiveness of different designs of stators for alternators.Winding factor is the ratio of electromotive force (EMF) produced by a stator having a short-pitch, distributed, or skewed winding, with a stator having full-pitch, concentrated, and non-skewed, windings.
In the very early days of commercial electric power, some installations used two-phase four-wire systems for motors. The chief advantage of these was that the winding configuration was the same as for a single-phase capacitor-start motor and, by using a four-wire system, conceptually the phases were independent and easy to analyse with mathematical tools available at the time.
In two wires running parallel next to each other, with the same alternating current flowing in both wires, the magnetic field of the adjacent wire induces longitudinal eddy currents in the wire which causes the current to be concentrated in a narrow strip on the side adjacent to the other wire. This has a similar effect as the skin effect; the ...

Shear and Bending moment diagram for a simply supported beam with a concentrated load at mid-span. Shear force and bending moment diagrams are analytical tools used in conjunction with structural analysis to help perform structural design by determining the value of shear forces and bending moments at a given point of a structural element such as a beam.
