I checked out JPCs on Youtube - I think there may be some limit to the responsiveness of materials as they get thicker, and rebar might be past that limit. |
|
|
Responsiveness meaning the tendency to revert to prior shape, not just deform to the new one? |
|
|
All that's going to matter is the young's modulus
which would be the same for the same sort of
steel. |
|
|
What I'm not sure would hold constant is the ratio
between the potential energy of the spring action
and the mass of the total structure, which would
result in
less energetic leaps. |
|
|
Also relevant would be the difficulty of twisting
the rebar so it's able to slip past itself on impact
like the paperclip can. Probably doable, but it's
going to be finicky. |
|
|
As you scale a design like this you're going to want
different properties from the material. You could
probably scale this using some plastic pipes/tubes. |
|
|
Could it be done with Pandrol clips ? That would be impressive, dangerous, potentially lethal, and extremely stupid and inadvisable [+] |

You can do this with trees, on purpose, too. Nothing like having a 3" thick branch brush the tip of your nose at 80mph. |
