Bridge design process

Bradlee CruiseMs. Fitzpatrick

3B

The class was tasked with constructing a bridge out of balsa wood under a budget of $160K

Define the problem

I know the bridge must be constructed using triangles to ensure stability

Brainstorm

The bridge must be functional, stable and be as close asPossible to the budget

Identify criteria and specify strengths

I know I can use different measurements on each piece to ensure stability while reducing the price significantly.

Explore possibilities

Make a small bridge using triangles to be stable and cost-effective

Select an Approach

Make a model or prototype

The bridge failed multiple times and needed much tweaking to make it functional

Test and Evaluate the design using specifications

I tweaked the measurements of each piece until it was stable enough

Redefine the design

My design was very successful and was in compliance with all criteria.

Solution

The bridge slightly exceeded the budget but was fully functional
