SUMMARY

The discussion centers on creating a science fair project inspired by the Tacoma Narrows Bridge collapse, focusing on the flutter effect and its implications for bridge stability against wind forces. Participants suggest alternatives to building a bridge, such as using a fan and a strip of paper to demonstrate the flutter effect in a cost-effective manner. The conversation highlights the importance of understanding aeroelasticity and its applications in engineering, particularly in designing structures that can withstand dynamic forces.

PREREQUISITES
  • Aeroelasticity principles
  • Understanding of wind forces on structures
  • Basic knowledge of model building techniques
  • Familiarity with experimental design and testing
NEXT STEPS
  • Research "Aeroelasticity and its applications in engineering"
  • Explore "Flutter effect demonstrations using simple materials"
  • Investigate "Wind tunnel testing for model structures"
  • Learn about "Small scale wind generators and their design"
USEFUL FOR

Students, educators, and science fair participants interested in structural engineering, physics, and innovative project ideas related to aeroelasticity and wind forces.

Homework Statement


Hi, i want to do a science fair project on the Tacoma Narrows Bridge Collapse. I want to do a research on the Tacoma Narrows Bridge collapse and how it taught us what structures stabilize a bridge against wind forces.
I also want to build something that would demonstrate the flutter effect. First i thought i should build a bridge and test it in a windtunnel, but i don't know what material i should use, and i think it would be expensive.

Homework Equations


The Attempt at a Solution


So, i was thinking about not building a bridge, but something else that would demonstrate the flutter effect, something that wouldn't be so expensive :)

Hi Azu! Welcome to PF! :smile:

If you want a project on aeroelastic flutter, how about going green o:), and following this up, from http://en.wikipedia.org/wiki/Aeroelasticity#Flutter" …
It is however not always a destructive force; recent progress has been made in small scale (table top) wind generators for underserved communities in developing countries, designed specifically to take advantage of this effect.[1][2]

A fan and a strip of paper, held at each end, might be able to demonstrate the flutter effect.
