Only the outside two are going to get much out of this, assuming the chairs are inelastic. |
|

T'would be more of a spectator sport were they elastic. |
|

Awww, and I was hoping you'd get it, [bigs]. OK, basically you
build
a large Newton's cradle, and people can sit on your balls.
Much hilarity ensues. |
|
| |
//people can sit on your balls// |
|
| |
Sure, we just encapsulate the passengers. In something. |
|
| |
Actually, you want elasticity. |
|
| |
Also, if you think about it, it's funny how Rubik made a
fortune from the cube, but Newton never made a penny
from his cradle. |
|

7.4, in old units. 7.6 if you're holding a cat. |

I’d have thought Dyson’s Sphere would have been a better corollary. |
|
| |
It's all yours, [bigs]. For tax reasons, I can't afford to earn any
more royalties on top of the legal settlement on the Welsh
National Peltier. |

Gonna need some pretty hefty airbags on those swingchairs if you expect _live_ people to use this for more than one swing. Which would tend to use up the initial energy pretty quick. |
|
| |
1m initial height, 50kg person = ~500J. |
|
| |
Balloons or springs would work fine. All you need is good
elasticity. |
|
| |
//Newton never made a penny// Not from the cradle, but he
made plenty of pennies. He was Warden of the Royal Mint. |

Not so. It depends on how many of the pendulums are raised in the initial conditions. You can pull back 4 out of 5 balls and release them. |

I wonder what the g loading would be one would
experience at the moment of energy transfer. |
|
| |
Actually, [MB} is right, as long as the collisions are elastic. And [RS}, g-loading (ac/de-celeration) will depend entirely on the rate of energy transfer. |
|
| |
Metallic balls stop dead in their tracks, and shoot off as rapidly, because the energy transfer is quite fast. |
|
| |
A more loosely coupled system based on elastic springs/balloons would cause the energy transfer to happen much more gradually. G-loading could be quite gentle, as long as one didn't lose too much of the original mgh energy. |
