The dead blow hammer is a useful tool. It delivers force
without elastic rebound meaning that peak force is
limited
and the length of the impulse is expanded. This is useful
for preventing damage to surfaces by delivering force in
a
long slow pulse.
The cat, when dropped, doesn't bounce.
They just sort of
plop down and then wander off. This is because they use
sensor fusion* accelerometry, optical rangefinding etc.
combined with learning neural net processing and active
feedback from the 4 force actuators situated at the
corners. While falling, the cat calibrates the 4 actuators
to
decelerate the massive upper portion within 4-6 inches
or
so. This is quite clever, certainly more sophisticated than
the usual sand/lead shot system. This could actually be
useful in industry.
Instead of a 15lb dead blow hammer, we take a cat of
similar weight. Using an adapter, the cat is attached to a
striking face. Now, when accelerated toward the target
surface, the cat would self-calibrate and deliver the
force
over a distance governed by leg length. More force? More
Cats. Longer impulse? Taller cat. Simple. For larger
industrial applications like foundation pile driving, a
pride
of lions could be employed.
* Come on Lockheed, sensor fusion... I think I had a
camcorder that did that.

I dunno, has anyone tested the Rockwell hardness of a cat's
skull? |

|

It is widely recognised that even dead, cats bounce - a
little. |
|
| |
Huh... I'd read that cat's could only survive an eight story fall but it turns out that's totally wrong. Their odds of survival get better from even higher falls. [link] |

ah, crap I clicked on it. |

Surely, she's not that bad? |

Using a 380mm BL naval rifle ? |

|

A live cat, or a dead cat ? Using one of those sharp pointy gadgets with the screw-clamp, like precision thumbscrews, with the dial gauge ? |

The data might possibly be available, if you ask nicely, it's unattributable, you don't ask any questions about how it was obtained, you have the ethics of a plague bacillus, and you're not part of any scummy cat's rights animal protection mob. |
|

|
| |
It depends very much on the height from which they are dropped, and the impact surface. Above 500 m, cats impacting a hard surface such as concrete tend to splatter, having attained terminal velocity. On soft surfaces such as turf, they become partially embedded, and don't bounce. |
|
| |
I find that the Rockwell test frequently catches the
creatures in a transitional state between living and
dead, and so the data forms a nice average. |
|
| |
//Above 500 m, cats impacting a hard surface such as

// |
|
| |
A cat will reach terminal velocity in something like 150-250m
of freefall. Terminal velocity will be on the order of 55-
60mph, which does not typically result in splatter. |
|
| |
Perhaps [8th] could rework the idea to achieve optimal
splatter, or would that be a completely different idea? |
