Uncompleted Tasks • • • Connecting Suspension All finalized engineering drawings Machining parts Analyzing Performance Stress testing of suspension Suspension performance

Team Improvement • Better organization of work time • Total group involvement

Next Semester Task • • Analyzing material stress/strain Material Selection Ordering parts Machining and assembly Analyzing Performance Stress testing of suspension Suspension Calculations Incorporation of Stirring System

Conclusion • Though the project is behind schedule for most groups on the solar car. We do hope to accomplish our over all goals that were set from the start. • This has also been a stressful but simulating learning experience.
