If you look at the loading of a steel bar, or a reinforced beam in civil engineering, a graph denoting the stress and reactions at various points of the subject in question is very common. Such a graph is obtained by calculation, not by cutting up the beam. When you put an object on a scale to find out its weight, you are actually looking at the reactional force exerted on the object in an equal magnitude but along an opposite direction; therefore, as long as we can pot a graph representing the reactional force at various points along the cue in relation to a loading, we can pot a curve to represent its weight distribution.
I believe graphs representing torque, bending stress, tensile strength, tensile stress...etc of cues are also possible, which hopefully, can help us to understand more about the performance of cues.
What do you think?
