What is the strongest bridge to make out of popsicle sticks?
Warren Truss bridge
A Warren Truss bridge is made with equilateral triangles that divide out the weight on the bridge. This makes the bridge really strong. To start, you will need two rows of popsicle sticks for the bottom base. Start by lining up three popsicle sticks end to end.
What is the strongest bridge design?
Truss bridges are extremely effective because they have a high strength to weight ratio. In this experiment we have tested which type of truss bridge is the strongest, yet uses the least amount of material. Two of the most used truss bridges are of the Pratt and Howe design.
Which bridge shapes and designs are the strongest?
The overall shape of many bridges is in the shape of a catenary curve. The catenary curve is the strongest shape for an arch which supports only its own shape. Freely hanging cables naturally form a catenary curve. The hexagon is the strongest shape known.
How many popsicle sticks do you need to make a bridge?
Cut three or four popsicle sticks to this length. If your popsicle sticks are too short, make a longer one. Cut two sticks and, with glue, join each by attaching another stick to the bottom for support.
What is the weakest type of bridge?
The weight placed on a beam bridge is pressed directly downward, toward any underneath support, which makes the middle portion of the bridge the weakest.
What is the most expensive type of bridge to build?
Suspension Bridge
Suspension Bridge Pleasing to look at, light, and strong, suspension bridges can span distances from 2,000 to 7,000 feet—far longer than any other kind of bridge. They also tend to be the most expensive to build.
What is the weakest 3d shape?
The Triangle is one of the most solid geometrical shapes. But it points out also the weakest areas in hitting, locking, stances, moving and so on.
What is the weakest bridge?
Beam Bridge
Beam Bridge Weight Distribution The weight placed on a beam bridge is pressed directly downward, toward any underneath support, which makes the middle portion of the bridge the weakest.
How big is the biggest popsicle stick bridge?
100 white glued popsicle sticks held the weight of a Horse (970 lbs). What could 4000 do? #Nationals At the 25 th Annual Popsicle Stick Bridge Competition held at the University of Alberta in 2013, Civil Engineering Student Tony Dong broke the record of highest weight at an astonishing 746 lbs (338kg).
How to make a truss bridge with Popsicle sticks?
We decided to make a truss bridge with our sticks. A Warren Truss bridge is made with equilateral triangles that divide out the weight on the bridge. This makes the bridge really strong. To start, you will need two rows of popsicle sticks for the bottom base. Start by lining up three popsicle sticks end to end.
Is there a weight limit on popsicle sticks?
The bridge will be loaded midspan, like a point load, and there’s no limit on the number of Popsicle sticks, but there’s a 1 kg maximum weight, so strength-to-weight ratio must be greater than 250.
Can a popscicle stick bridge be made without cables?
No matter how strong the theoretical design of the bridge is, and no matter how strong the individual sticks and cables are, they will be nothing if the connections fail prematurely. Gluing sticks together on their face is fine, but I suggest taking it the extra mile and drilling the sticks and creating tiny doweled connections.
