Popsicle Stick Bridge - Engineering Assignment 2009

[MrCoolios12]

@6:43 to see what you actually came here for

[OptOut17]

Nicely done. Below is a link to a similar bridge I built.

Do you have the plan for the popcicle bridge and can i have it, if you got it

[FalconGaming]

@01Dyduki01 I dont have the plan on me. What I did was create the template on paper then using aluminium angle created a physical template to lay the sticks in and then built it up from there in layers. I am not sure when I put the paper template but the design isn't too complicated s you can see from the video. I will see what I can do about finding the design

[01Dyduki01]

@FalconGaming well you did a nice job for the bridge

[kunalxxx1]

Thanks a lot for helping.We are forward to a bridge which can take around 200Kgs, i think length is a big concern in truss bridges and there a limit of 100 to 250 cms.What should be the length according to you?

[kunalxxx1]

can i get d design or jst tell how u actually joind these sticks..have 2 do for a project

[FalconGaming]

@kunalxxx1 How it was designed so that each popsicle stick would overlap the previous stick at half way making the most of the surface area for glue. Then it was simply build in layers. The design of the bridge is a simple truss. Look at the bridge in the video and you can have a rough guess on how many popsicle sticks you need downward then work your way around. We used araldite as our bonding agent. I am always interested in hearing how others when in recreating our bridge. Good Luck

CAn i get the designs for this bridge? Awesome design

[fordlukebo]

DAMNNN!!!

[FalconGaming]

@fordlukebo Whats up?

[bulbulahamadnz]

hey mate..excellent design..do u still have the calculations for it?

[FalconGaming]

@bulbulahamadnz What kind of calculations do you require?

[bulbulahamadnz]

@FalconGaming calculations of your expected failure load. I designed lyk yours...and the failure load I got was 135 kg, but last week after the test, it actually took 270 Kg and den it snapped.

I must have stuffed up my "I" value..

[bulbulahamadnz]

@FalconGaming and did you say in you addendum report? Was the failure triggered by shear or bending stress?

[FalconGaming]

@bulbulahamadnz The assignment that I constructed this for was to put a practicality of our theoritical side of the assignement. We were not require to write a report about the bridge and the problems assoiated with the construction and final cause of destruction. Looking at the bridge now, it seems that the major failure was in its centre supports at the glue joints. Though I have to mention that several of the centre supporting stick did break. So i would say bending stress here.

[Rand0mAsian]

o.o thats pretty strong, we had to build one for our first year engineering course here in New Zealand. our bridge had to be less than 150g.

we held 680Newtons (around 68kg) today =D really happy results

did you get a good mark for your assignment?

[FalconGaming]

@Rand0mAsian Yeah I got top of my class. 50/50 for the Bridge then we had a written part which i did ok in.

[thatgurl54]

i saw this on a forum but i cant remember the exact website, can you give me the link please?

[FalconGaming]

Garetts Bridges

[FalconGaming]

My dad was filming it and also counting. I know of another way to make it even stronger but that will be for later.

[BowlingFreak218]

can you please tell me how you would make it stronger? because im going to make this bridge bsince i saw the phto of it and details on garetts bridge.

[FalconGaming]

Well potentially using super strength araldite instead of the 5 minute stuff might help, though there is certain structural changes that could be made but I haven't gone into depth yet.

[BowlingFreak218]

lol would you like to go into depth?

[Tiepan]

Outstanding design. Hope the American institute of Engineering is watching :) You never know...you might get hired.
