Overview |
|
First 4 coin span bridge |
|
After the 4 coin span collapsed |
|
First attempt at a 6 coin span.Didn't like this one, it's not very elegant. |
|
Closeup of the centre |
|
Attempt of an overhang |
|
Underneath shot. It was overhanging by 2 coins but then collapsed because there wasn't enough counterweight.' |
|
Beginning construction of the new 6 coin span. This was the 2nd attempt of this design, here I have nearly run out of coins and decided to go to the bank for more |
|
More construction after I got back |
|
The two sides meet. This bridge was far more stable than the last, each side could freely support itself right before the meeting. The other bridge had supporting 'scaffolding' during construction. |
|
Adding more coins |
|
I added more coins on top in the middle I found the bridge became stronger. I added more coins until the top of the middle was level with the sides. |
|
Finished |
|
A closeup of the span |
|
A dome of some sort with a joining coin spiral and bridge connecting the two. The dome is hollow! |
|
An attempt at making an arch style bridge of sorts. No luck, this was really unstable. |
|
The coin spiral on teh side and close up |
|
A view of the inside of the dome (well as much as possible) |
|
An upside down version of a bridge I want to make, two lanes. (with one column support) The coins interlock in a nice way |
|

|
Preliminary testing of the support. I really didn't think it would be possible to balance two lanes of coins on a single column but was pleasantly surprised to find the interlocking system of the bridge hold the coins up well on the single column |

Coin pyramid under construction (9 coins high) |
|
Another shot |
|
Maximum size. This is solid, so it takes a lot of coins. It's 11 coins high, seems so small :S |
|
Diagonal shot |
|
Added an odd bridge thing |
