I have always wanted to construct a design suspension bridge, and finally I have finished one. This is a popsicle pole suspension bridge. I produced it indigenous scratch, comes up with the design on my own. After experimentation it come failure i learned quite a bit about how suspension bridges react to loads. This version suspension bridge provides popsicle sticks as the main structure material. The decking is cardboard, and the “cables” space 550 parachute cord (military surplus).

Testing the Suspension Bridge
Here is the video of the leg being tested to failure. I have actually two different angles verified right after each other. Ns think this video clip is really enlightening regarding how a suspension bridge reacts to a load.
It appears that the bridge failed because of uneven loading. The weights leaned to one side, and also I over-corrected together I kept including weights.
I did no come up with a great method of securing the cables to an anchor. Friend will an alert in the movie that the end of the leg lifted up together the center bent down, till a details point wherein the ends of the deck pressed up against the cables themselves. If i were to do this again, ns would have the cables already pressing down on the end of the deck to help secure it in place. I think this would provide much far better support come the bridge fairly than what ns did.

This suspension bridge was an extremely flexible, as you deserve to tell native the video. I read an article about building design suspension bridges that claimed it was an overwhelming to gain them versatile enough. Also, i did no have any type of hangers (vertical cables hanging off the main cables) on this bridge. I did no make any kind of mostly because of the great an obstacle in making lock even and also I walk not understand a good way to attach the hangers to the main cables. In real life, the cables room metal and also have metal clamps and other tools that make this process easier. Yet I was making use of parachute cord.
Plans for this Suspension Bridge
Do you want to develop a version of a suspension bridge? they sure space fun and are good to look at at as soon as you space finished. Mine models are always functional, which method you deserve to test them together well. When I do not have blueprints because that this details suspension bridge, ns do have actually plans for a smaller sized one. Girlfriend can examine them out here:Suspension bridge Blueprints
