In cargoland there are numerous tall buildings, many being 50
floors
and greater in height. Although most of these vertical
monstrosities
are vulgar eyesores, they nevertheless present the perfect
opportunity to facilitate the idea of having A Long Slow
Comfortable
Swing.
To complete
the proposal, all that's required is an area of obstacle
free public space immediately adjacent to a very tall building. A
substantial horizontal girder can then be added to one of the
uppermost floors, projecting outwards and overhanging the space
below. Attached to this girder are pairs of hanging chains, each of
which terminates in a very comfortable seat positioned a few feet
from the ground.
This are the seats that provide for their relaxing occupants the full
experience of A Long Slow Comfortable Swing, as they lazily
oscillate
backwards and forwards, confirming the periodic time of the most
satisfying of equations: T = 2 x pi x the square root of L / G
The perfect cocktail to serve

Make it just hang from one cable, and have a time-
pendulum. Of course now you need a mich stiffer
girder, and a circular footprint. |
|
| |
If two buildings are near each other and both are at least a
suitable height (they don't have to be the same height;
they just need to be a minimum height), then some sort of
girder spanning the gap between the buildings could be
installed, and several swings hung from it. |
|
| |
Better make it pretty heavy or basically rigid because otherwise the slow and comfortable is going to be replaced with violent harmonics and lethal responses to slight breezes, breezes found to be frequent near large structures. |
|
| |
This is one way to measure the height of very tall
buildings...height in m = 1/4 of time squared. |
|
| |
An interesting way to commute. |
|

Like George of jungle without the tree. |

Oh the options for vandalism... |

Is the cocktail served while I relax in the motion? |

How will the swingth be generated? |
|
| |
Some time ago, I built a super-duper swing
suspended from
the branch of a beech tree - it was about 40ft
long. It then
transpired that it is almost impossible to generate
swingth
with such a long rope, unless either someone
pushes you or
you can scrabble your feet along the ground. |
|
| |
I suspect that this problem could be overcome by
having
some sort of motorized cam that moved the
attachment
points back and forth at exactly 2 x pi x root L / G |
|
| |
Maxwell, I suspect that you needed around 3/4 ton to get a smooth swing at that distance. |
|
| |
Slightly more that's required: an arc of flooring beneath the path of the swing - even with a small angle of deviation, the occupants would be a very long way above the ground. |
|
| |
Also, I think you'd need rigid supports for the seats, or the swing will end up swinging from only part way up and you'll just wibble around like a fish on a line. |
|
| |
The supports would need to be very inelastic so that the weight of the occupant didn't make the seat drop significantly when they got in, or on hot days. |
|
| |
I like to imagine that it would be a whole swinging platform, since the rest of the structure is so large, and because you couldn't possibly have several swings which didn't collide. |
|
| |
Maybe we put the bandstand on the platform, then the band can REALLY swing. |
|
| |
Shouldn't that be measured in Newtons? Oh, you mean you need 675 kilograms of weight on the platform? And then it would swing smoothly? |
|
| |
Elegant. A more complicated way to build this might
be a gently curved
pair of rails supporting the ends of the swing seat,
so the seat moves through the same arc as if it were
attached to a 50-story cable. Bearings would need to
be low friction. |

New tons? I just got used to the switch from Imperial Tons
to Metric Tonnes. No Voice wants to bring in 'New Tons' |
