Bridge Presentation

 First, give some background on the bridge you decided to recreate.

Discuss the general form of the bridge, and other similar structures.

Talk about the trouble areas that showed up after your first FEA analysis.

 Outline what design modifications you implemented to make the bridge more stable.

Compare FEA results between the modified and unmodified bridge.

 Additional modifications:

 Hold the loading force and material constant so you can directly compare the different bridge designs.

 Redesign to eliminate "red" zones.

 Goal - (almost) solid blue - homogeneously distributed weight.

Once your design is satisfactory, compare the same design made up of different materials.

Double click on your material to view the strength and mechanical properties.

 Review what these properties mean!

 Create a table in excel to compare and contrast different materials.
Note:  Results might be very similar!  Look at the displacement results. 

Do a vibrational analysis

 Are the bridge natural frequencies in a range you will have to worry about?

Test your bridge to see how it reacts to different loading scenarios. 

Car accident above?  Boating accident below?  How will your bridge react if a chunk of it is destroyed?

Create a ~ 5 minute Power-Point presentation
- Use google images
- Use the snipping tool or screen capture

- Include minimal text (this will keep you from just reading off of your slides)

Be prepared to present your bridge next Tuesday!

A few thoughts on presentations...

Very few people like to get up in front of an audience, and no one is perfect... but if you don't present it, you won't get credit for it!
