Some photos of LegoWorld 2005 Bridge strength contest, and of the arched
bridge that I built for it are [<http://philohome.com/bridge/bridge.htm

WOW! That's very impressive. (yeh, I know- I'm a little late in posting this.
:-) It has a nice shape and looks very stout. The relatively large height
(compared to the span length) gives it a lot of strength. I like how you doubled
some of the chord members to eliminate the eccentricity.

Thanks TJ!

I'm glad you found my spreadsheet of some use ;-)
Yes, it was very helpful to optimize member length to minimize members splits
and match my parts collection!


Regarding the contest, I think if the bridges had been judged on a weight to
strength ratio, yours probably would have won!

I don't think I would have won... this bridge
http://philohome.com/bridge/marc.jpg had about the same weight but was stronger.
Anyway I prefer the look of mine ;o)

But indeed we should have limited the maximum weight of the bridge (2kg would
have been fine for that gap length)
