An American would look at it and say that the easiest way to do it would place a toggle between point A and point B. A German would look at it and see that by connecting a toggal from a to c and another from C to B it would reduce the stress on point D and be more German.

You can even see the same thing with cars. Ford does it one way, Chevy another, and Chrysler another way yet. Each has its own engineering 'culture' that is differnent and gets passed down over the years.
