"It wasn't clear how/if the cable was restrained when you flicked it. In other words, was the loop of cable resting against a hard surface, and you flicked the stationary cable? That's what it sounded like, but I wanted to clarify."The coaxial loop was held in my left hand in free space. That way, the loop could squirm in my hand when struck. I was concerned about permanently deforming the cable by striking it against a hard surcface or hard mounting it so that a secondary bend point would be created, although I'm sure it still did to some degree and may be partially responsible for some of the ringing seen in the waveform. So the force would have momentarily caused the coax to buckle at the point of impact before it's mass was overcome by the striking force and setting it into motion.
Man, some high speed movies would have been awesome.....
