Readers ask: How To Build A Suspension Bridge With Popsicle Sticks?

How do you make a strong bridge with Popsicle sticks?

Cut one stick in half using a large scissors. Glue the halves to each end of the 3 sticks placed end to end and glue two popsicle sticks in the middle. Glue three more full sticks on top to create three layers with overlapping joints. Repeat this 3 more times to create four 3-popsicle stick beams.

What is the strongest Popsicle stick bridge design?

The 100 stick popsicle bridge challenge is on. This Howe Truss bridge uses 99 popsicle sticks, spans 21 inches, and holds 200+ pounds. It’s efficiency score is 678. This is an updated version of my old “Popsicle Bridge #3” which was the same length, but slightly different in construction.

How do you make an arch bridge out of popsicle sticks?

  1. Cut rounded edges off four popsicle sticks so the sticks are 4 inches long, and place them in warm water for five minutes.
  2. Cut rounded edges off 68 popsicle sticks so the sticks are 4 inches long.
  3. Stack center of the bridge to create the high arch.

Which type of bridge can hold the most weight?

The arch bridge can hold the most weight of the three, the deck truss bridge can hold an average amount of weight, and the beam bridge could hold the least amount of weight. This experiment tested the arch, deck truss, and beam bridges to see which could hold the heaviest amount of weight.

How do you make a strong bridge?

While connecting two sides, make triangles. If you really have time and want your bridge to be very strong, you may also divide each triangle to 3 smaller triangles. This will give additional strength to your bridge. You may also glue additional strips of pasta over the roadway.

What type of bridge is the weakest?

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 2 forces act on a bridge?

The answer lies in how each bridge type deals with two important forces called compression and tension. Compression is a force that acts to compress or shorten the thing it is acting on.

What design shape supports a bridge the best?

It is impossible to collapse a triangle without breaking one of its sides, which makes it the strongest straight-edge shape. For this reason, you will see triangles in lots of bridges. Triangle shapes in a bridge direct the weight of the bridge and the cars crossing it downward without bending.

What materials are used to build a suspension bridge?

A suspension bridge can be made out of simple materials such as wood and common wire rope.

  • Longer main spans are achievable than with any other type of bridge.
  • Less material may be required than other bridge types, even at spans they can achieve, leading to a reduced construction cost.

How do you build a straw suspension bridge?

Try It Out

  1. Cut two short pieces of straw, each 3 centimeters (about 1.25 in.)
  2. Tape one tower to the edge of a desk or chair.
  3. Place another straw between the towers so its ends rest on the short pieces.
  4. Make a load tester by unbending a large paper clip into a V-shape.
  5. Now change the beam bridge into a suspension bridge.

How does a suspension bridge work?

Suspension bridges get their name from the fact that the roadway is suspended by cables from two tall towers. Most of the weight is supported by the two towers. They, in turn, pass the compression forces from the cables directly into the ground. These run vertically from the deck up to the main supporting cables.
