And, again mirrored by a formal flexion x force graph of the same rods.
Fig. 8
Looking again at figures 5 and 6, one is struck by 1) the general overall shape of the rods in full flexion is generally similar and 2) the most obvious difference is in the degree of flexion most accurately and mechanically stated as the degree of shortening!
One critical assertion stated above and visually apparent here is that all the differences between rods, in taper, materials, modulus, and tip weight merge and stabilize into a single mechanical unit and are not recognizable other than a difference in total flexion, or stated mechanically, simple differences as a shorter or longer “device“ with a single mass.
