BRIDGE BUILDING CHALLENGE

Tech Edby Mr. Atkinson

Your engineering firm has been challenged to design a bridge that spans 16 inches using a maximumof 100 popsicle sticks. Thinking back on what you've learned so far about bridges, begin by exploringconcept ideas through sketching. Submit the sketch you are most happy with to Ms. Gregson or Mr.Atkinson for approval before moving on to the drafting stage. You will need to draft a side, top, andbottom view of your bridge at half-scale.

When the drafting is complete, you will have the opportunity to pair up with a friend and proceed ontothe building stage. No materials other than glue and 100 popsicle sticks are permitted in the bridgeconstruction. However, once your bridge is built, you may decorate it with felts or paint.

Once all of the bridges are finished, we will have a gallery showing of the completed bridges. Thebridges will be self and peer reviewed for aesthetics (how they look). Following the gallery showing, allof the bridge submissions will be tested to see how much weight they can hold!

Points will be awarded based on sketches, design, drafting, effort and craftsmanship/appearance,and ability to bear the most weight. The final mark will be based on peer review, self review andteacher review.

Design should include elements learned in class (truss, triangles, sway bracing...)

Minimum of 3 sketches required

At a Glance

Overview

No materials other than glue and popsicle sticks permitted in final construction

Bridge needs to include a deck so that a 'hot wheels' car can drivefrom one side to the other

Bridge must span 16 inch gap, therefore should be at least 18 inches long

Be creative and have fun!

Drafting must show a front, top and side view at half scale

Steps to Success!

Helpful Tips

Peer Review

Do some research on your own before you start. There is tons of info out there!

Triangles are the strongest shape

Think back to edge grain vs. face grain

Sway braces are very handy!

Remember, bridge must span 16 inch gap, therefore should be at least 18 inches long

Trusses are super cool!

Laminated beams are super strong!
