  1. Concepts of Planning & Designing Tahiem Williams Science Undergraduate Laboratory Internship August 14, 2008

  2. Overview • Objective • Introduction • Background Information • Procedure • Data/Observation • Results • Conclusion • Acknowledgements

  3. Objective • 30ft Ladder Evaluation • Relocate 6 inches from the wall 12” Steel Rod

  4. Objective • Surveillance Camera Design • Brainstorm ideas for Radio Frequency (RF) Distribution Structure

  5. Introduction • The Phases of Design • Recognition of need • Definition of problem • Synthesis • Analysis and optimization • Evaluation • Presentation • Oral • Writing • Graphical

  6. Background Information • Ladder Evaluation • Weight • Density of Steel:

  7. Background Information Cont. • Shear Stress – stress applied parallel to the face of a material • - the applied force • - area to which the force is applied • Moment of Inertia – rotational analog of mass • - the diameter

  8. Background Information Cont. • Maximum Deflection • - the elasticity of the material • - the length • Bending Stress • - the moment of fixed ends • - the perpendicular distance to the neutral axis

  9. Procedure • Surveillance Camera Design • Excel Spreadsheet • Presented to others • Installation • Radio Frequency Structure • Aluminum Sheets • Measured sections of RF • Drew Sketches • Sent to machine shop • Installed

  10. Data/Observations • Surveillance Camera Design

  11. Results • Ladder Evaluation

  12. Results • Surveillance Camera Design • End Station A • Ethernet Crossover Cord • Same function as Straight-through Ethernet Cord

  13. Results • Radio Frequency Distribution Structure • Aluminum Sheets

  14. Conclusion • Ladder Evaluation • Ultimate Stress of Steel: • L – Brackets were installed to relieve stress L-Bracket

  15. Conclusion • Surveillance Camera • End Station A

  16. Conclusion • Radio Frequency Structure
