Making the Longest Truss Bridge with Craft Sticks!

[@StructurePlanet]

Using the normal craft stick is possible but they are a bit shorter (1.5" or 3.8cm shorter) so you may need more pieces to get the same lengths or just reduce the scale by that much. For the glue, the Gorilla brand general glue is pretty good for this purpose. For other general purpose glues, I would just do a quick test by gluing two sticks together (1/3rd of lengths overlapping) and try to separate them by pulling it from both ends in the same direction as the sticks. If it gets separated easily, it is not a suitable glue.

good one

Congratulations, you have spent 127 dollors worth of popstical sticks and glue Good job btw

Using high strength wood glue will be stronger than using glue sticks!

How many popsicle sticks for a bridge a little smaller

[@StructurePlanet]

Mine needed about 1000 Popsicle sticks.

[@dicidsisi]

Wow I made my bridge and it was so fun I used 500 popsicle sticks

[@AvgSummoner]

Wow, i have a similar project for engineering design and it says that the bridge shouldnt exceed 250gms, so please help out

[@StructurePlanet]

I have made one which is less than 200 grams. Please watch it here kzbin.info/www/bejne/rp3ac6Com5tlapI

@@StructurePlanet awesome, thats exactly what i need, thanks!!

[@ShalomAdetula]

awsome

[@hansmadredio8429]

I have an project and a I use your idea

[@neercj]

Is is possible to build like this but it is 1 ft or less than 2 ft? Need for project

[@StructurePlanet]

Hi A J. Yes. It is possible. If you want to reduce the span of the bridge by a large number, I suggest to reduce the depth and width with about the same ratio as well so it all look kind of proportional.

[@neercj]

@@StructurePlanet will you please elaborate more on how to reduce the depth and width with the same ratio? Thanks :>

[@StructurePlanet]

Hi A J. What span do you want for the bridge?

[@neercj]

@@StructurePlanet something like 1.5ft

[@StructurePlanet]

Well 1.5' is way smaller than the original design so you will need to use smaller stick types. If you want to achieve somewhat similar proportions, I would say make it 3" deep in middle, 1.5" at ends and 2.5" wide. However, depth has a direct relation to the strength so maybe a 4" middle, 2" end and 3" wide is better.

Can you do this but without so many popscile sticks

[@StructurePlanet]

Sure can but it may reduce the load capacity unless you are referring to the sticks I used for the deck which are non structural.

[@heamenpaulo7877]

how many pop sticks total?

[@StructurePlanet]

Based on the Popsicle pack I had at that time, I would say about 1000.
