8. Project Teams n Teams of 3 (and 4) n Project Groups n Goal: –To discuss, decide, and to do real work together n Rotating Leadership –Studies have shown that rotating leadership assignments in semester-long projects works well –Every member has an opportunity to be the leader for at least one reports

9. Project Selection Criteria n Design Against Failure n Geometry Complexity n Load Estimation n Operating Conditions n Material Properties n Functional Behaviors: –Elastostatic analysis –thermal analysis –Buckling & Free vibration

10. Project Information n Goal: –Product Redesign requiring design, analysis, and evaluation of one or more special purpose parts n Project Proposal n Force Model & Solid Model Report n Analysis Report n Final Report n Sideview Mirror

11. Project Evaluation n All reports will be evaluated based on: n Substance: Quality of contents and quality of drawings n Style: Presentation of materials in an integrated manner that is easy to read with no spelling, grammar, or, other errors

12. Project Proposal n Two-pages to include:  Member names and rotating leadership assignment  A brief overview of your design describing:  General functions, operating conditions, and overall objectives of your project  A sketch of the Actual Part or subassembly  Project Timeline with task schedule

13. Force Model & Solid Model Report n Group report with a leader clearly identified n Suggested topics: –Introduction –Objectives –Plan of Work –Force Model n FBD based Force Analysis –Solid Models of critical components n All figures should be numbered and have figure captions –Conclusion

14. Project Analysis Report n Group report with a leader clearly identified n Improved Solid Model Report n PLUS: –FEA of critical components n Discuss in detail your simplifications in the context of your design objectives n Clearly detail load conditions n Discuss and kinematic constraints –Validation of your results using simplified hand calculations –Conclusion
