ive always wondered if the double impact principle had any basis in real life. used by sanosuke and anji in rurouni kenshin, the techinique, regardless of how completely humanly impossible it is, is as follows - the user hits twice in extremely quick succession,, the second blow hitting the target before the initial impact energy of the first hit dissipated. the desired effect is basically the disintegration of the target.
from what i can see, the second impact should hit faster then the speed of sound in the impact space that matter, since energy would propagate through the matter at that speed. that would be absurdly fast, in say wood or stone, since sound travels through those matters in speeds exceeding 20 000 feet per second. in theory, if the target space is 1/4th of a foot, and the speed of the soundwave in the matter is around 20 000 feet per second, you would have to hit twice within 0.00008 second to achieve the desired effect.
id still want to know if the desired effect would be as spectacular as shown in fiction.
i want to try it out with mechanical devices. im thinking of a cylinder with a weight on one end, and within the cylinder is a steel sphere. the combined weight of the cylinder and the weight is equal to the sphere. you mount the cylinder on a handle, much like a hammer, and swing it on a target.(the whole cylinder/weight/sphere would weight about a kilo, and the handle would be very long, as to increase speed at impact) the weight impacts the target, then the steel sphere hits the back of the weight, and in turn, the weight hits the target a second time within a short span of time. depending on the setup, i hope to get cool results.
as a control experiment, i will perform the same thing but with a solid cylinder that is equal to the weight of the other cylinder/weight/sphere. with the same dimensions and the same speed at impact, i hope to get different results.
the only difference between the two experiments will be that the control experiment will hit once with 1 kilo, and the other will hit twice with 0.5 kilos.
