What is the strongest bridge to make out of Popsicle 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.

What popsicle bridge can hold the most weight?
Maximum Allowable Bridge Weight = 12 oz (340 grams). Note that a typical 4½ inch popsicle stick weighs approximately 1.3 grams. weight of the testing device (deck and connections) are not included in the final weight. gun) are allowed.
How do you make a strong bridge with Popsicle sticks?
Cut four popsicle sticks in half. Place each of the halved popsicle sticks at both ends of each of the truss beams, in the middle position of the three-wide popsicle sticks. The component three-wide popsicle sticks of each truss will be glued together to form a truss three sticks thick.
What are the three strongest types of bridges?
My hypothesis was that the arch bridge would be the strongest. The experiment involved building and testing the strength three bridge types (arch, beam, and truss) by increasing the amount of weight on each bridge while measuring how much each deflected (bent), and at what point the bridges failed (broke).
What is the strongest material to build a bridge?
Best Material for Bridges: Steel Steel is a versatile building material, used for centuries in various capacities. Its strength and permanence are ideal for long-lasting structures, like bridges. The use of steel for bridges replaced earlier materials such as wood, concrete and stone.Apr 29, 2017

How much force can a popsicle stick hold?
The ultimate tensile strength for one piece of Popsicle stick was found to be 3.64MPa ± 0.27MPa (Mean ± SD). All samples fractured at the point where the load was applied.
What is a Howe Truss bridge?
A Howe truss is a truss bridge consisting of chords, verticals, and diagonals whose vertical members are in tension and whose diagonal members are in compression. The Howe truss was invented by William Howe in 1840, and was widely used as a bridge in the mid to late 1800s.
What truss bridge design is the strongest?
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. Through our experiment it was found that the bridge design that minimized the maximum compression force was the Howe Bridge.
What is the strongest bridge in the world?
Firth of Forth Bridge Notably one of the strongest bridges in the world, the Firth of Forth had to be strong since its primary function was for railroad loading. Today, this Highlands workhorse still supports between 150 and 180 trains each day taking people from Glasgow to Edinburgh and all stops in-between.
How do you make a bridge stronger?

But not all bridges are made of trusses.
What is the difference between a triangle and a popsicle stick?
Be sure to incorporate lots of triangles into your bridge design. More popsicle sticks doesn't necessarily mean a stronger bridge.
Why is it important to clamp a popsicle stick?
Clamps are important because most of the popsicle stick aren't flat, so if you don't clamp them when you glue them together your bridge probably won't hold together very well. Don't pinch your fingers. Keep your workspace clean! I glued everything on top of a piece of paper, as I have a tendency to get glue everywhere.
How to make a popsicle stick truss?
Start by lining up three popsicle sticks end to end. Glue on two overlapping the seams. Then cut one stick in half for the two ends. Repeat this three more times. You will then make two more with just two popsicle sticks making shorter beams. These are going to make the trusses.
How to make a 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. Glue on two overlapping the seams.
What is bridge building?
Bridge building is a great STEM engineering project for students. It is a simple way to teach about how important structure is to strength. You can build a bridge many different ways, and they will not all be equal. Take this bridge building project a step further by competing with other bridges to see which one hold up the most weight.
Is a popsicle stick bridge strong?
Yes, our popsicle bridge is messy and crooked, but my kids had a blast making it and it is strong! All you need to make this popsicle stick bridge is a good strong glue and some popsicle sticks.
How to strengthen a bridge if you can't use a dowel?
If you can’t use a dowel, you might still be able to strengthen the joints by drilling them and running a tiny piece of cable through as a tie. The connection where the main cable ties meet the top cord of the bridge at the two bridge ends is the most important connection on the structure.
Do popsicle sticks fail?
The math is too complicated to go into, but suffice it to say, if you keep the holes small enough, the Popsicle sticks won’t fail locally at the holes. These holes will reduce the weight of the bridge a small amount, increasing the efficiency. Finally, when installing the bottom cable, do not allow any slack in it.
How to make a popsicle stick bridge?
How do you make a strong Popsicle Stick Bridge? Lay out the Popsicle sticks on the pieces of paper on top of the scale designs. Glue the pieces together using white glue and allow to dry overnight. Assemble the bridge and glue the bottom and side pieces into place.
How to make a bridge with white glue?
Glue the pieces together using white glue and allow to dry overnight. Assemble the bridge and glue the bottom and side pieces into place. Examine the design and see if once assembled you can identify any weak points in your design. Click to see full answer.
Why are triangles in the arch of a harbour bridge?
Triangles on the harbour bridge are in the arch because the arch need to be strong in order to keep the bridge up and carry the load. An arch is useful because it transfers the load instead of focusing the load on one spot. Similar Asks.
What glue is used to build bridges?
The weight of the testing device (deck and connections) are not included in the final weight. Glue: Only wood glue (or Elmer’s glue) and hot glue (hot glue gun) are allowed. Elmer’s wood glue is recommended.
How wide is a bridge?
Bridge Rules, continued. The bridge shall have a clear 3 inches wide by 3 inches high opening passing through the bridge (end to end) to allow for the passage of a vehicle or the deck must be constructed on the top of the bridge.
