Popsicle Stick Bridge - Engineering Assignment 2009

My year 12 Engineering Assignment was to built a bridge that weighed less than 400g with a span of 600mm(24 in).

The video shows the test of the bridge weighing 361.6 g which held a weight of 251.5 Kg (553 lb).

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

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

@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

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

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

@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?

CAn i get the designs for this bridge? Awesome design

@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.
