# What is the strongest Popsicle stick bridge design?

Howe Truss Bridge

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.

Subsequently, question is, what is the weakest type of bridge? Beam Bridge

Beside above, how much weight can a Popsicle stick bridge hold?

Mere 100 popsicle sticks can be arranged and glued together into the style of Howe Truss bridge that can by itself carry the weight of over 200 pounds. Large and more elaborate popsicle bridges can withstand the weight of over 3,000 pounds!

What is the easiest bridge to build?

Beam bridges typically span up to 250 feet, and they’re also the cheapest and easiest bridges to build.

### What makes a good strong bridge?

Triangles make for a strong structure because the work off compression and tension. 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.

### What type of bridge can hold the most weight?

In conclusion, straight bridges ( truss bridges) hold the most weight. While I was doing this project i learned that straight bridges are some of the most strongest bridges in the world. Arch bridges are also strong because they have extra support at the ends, but truss bridges are usually stronger.

### What makes a bridge stay up?

An arch bridge supports loads by distributing compression across and down the arch. The structure is always pushing in on itself. The towers (piers) of a suspension bridge are in compression and the deck hangs from cables that are in tension. The deck itself is in both tension and compression.

### How do you design a truss?

Quick Steps of Truss Design Process Step 1: Model walls, roofs, ceilings, floors and main beams. Step 2: Generate truss areas and trusses. Step 3: Generate truss members. Step 4: Check connections between members. Step 5: Check supports. Step 6: Generate truss labels and drawings. Step 7: Generate internal pressure area.

### How much weight can a truss bridge hold?

Truss bridge number one held 24 pounds. The second truss bridge held 23 pounds so the average weight held by the truss bridges was 23.5 pounds.

### How does a box girder bridge work?

A box girder is formed when two web plates are joined by a common flange at both the top and the bottom. The closed cell which is formed has a much greater torsional stiffness and strength than an open section and it is this feature which is the usual reason for choosing a box girder configuration.

### How do you make a easy Popsicle stick house?

Here’s what to do: Make two rows of 15 popsicle sticks next to each other, tip to tip. Take one new stick and put glue on the entire flat side. Place the glued stick on top of a pair of sticks. Put glue on the entire second side of the stick that’s glued on the first pair.

### How do you make a strong spaghetti bridge?

Lay the spaghetti strands over your drawn design to cut them to the right length and glue them together. Make use of trusses to make your bridge stronger. Trusses are triangle-shaped support beams that attach point-side down to the roadbed of the bridge on either side. Attach the trusses to each other with glue.
