3. Overview Schedule Frame Analysis Attenuator Carbon Fiber A- Arms Conclusion

4. Schedule

5. Frame Computer Analysis Complete! Actual Testing of Main Hoop Hard Test starts Nov. 19 th using strain gauges Horizontal bending Longitudinal Torsion

6. Frame continued Quality Assurance 2 of 4 QA tests complete Weld Quality, (in progress) 37 of 42 test sites completed 8 unsat, (Being Fixed) QA still in progress Welding finished soon Wall Thickness (Pending) Alternative Frame Rules, (50% done) Proposed Method based on Hard analysis results.

7. Attenuator Materials Difficulty Estimated ship time 2 days Changed to 2 weeks! New Material Galvanized Steel 25 mm thickness, 1” cell size Current Status Fabrication completed! Soft Testing calculations altered Hard Testing moved to next week

8. Carbon Fiber A-arms Actual testing of assembly, Nov. 9 th Verify will meet track conditions Destructive testing required for 1000 lbs Going to complete testing and fully analyze, SF=1.2

9. Conclusion Frame  Weight test Nov 19 th Attenuator  Drop test next week A-Arms  Pull tests Nov. 9 th Complete the paper!
