This point is well illustrated by figure 1.1 showing a diesel engine connecting-rod design which failed in a direction that superficially seemed to be under very low stress.[1]

If we merely study analysis of standard cases we may fail to develop either the creative aspect or the knack of spotting weaknesses before they arise in the real object. This point is well illustrated by figure 1.1

Klaus Bichler,Ralf Krohn,Peter Philippiess due to this weight is something like 40 N/mm. on top of the duty stresses due to load, inertia and curvature. When we consider tethering a weather balloon, dredging samples from the sea bed or drilling deep holes, we need to consider tailoring the rope or drill pipe to the duty in more detail.

Many students are taught to use Macaulay’s method and the three moment equation. These excellent methods have the following disadvantages: they do not aid a sense of structure, they are lengthy, errors are difficult to
