Objective
• 30ft Ladder Evaluation
• Relocate 6 inches from the wall

12” Steel Rod

Objective
• Surveillance Camera Design
• Brainstorm ideas for Radio Frequency (RF) Distribution Structure
Introduction
• The Phases of Design
• Recognition of need
• Definition of problem
• Synthesis
• Analysis and optimization
• Evaluation
• Presentation
• Oral
• Writing
• Graphical
Background Information
• Weight
• Density of Steel:
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
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

Procedure
• Surveillance Camera Design
• Presented to others
• Installation
• Radio Frequency Structure
• Aluminum Sheets
• Measured sections of RF
• Drew Sketches
• Sent to machine shop
• Installed
Data/Observations
• Surveillance Camera Design
Results
Results
• Surveillance Camera Design
• End Station A
• Ethernet Crossover Cord
• Same function as Straight-through Ethernet Cord
Results
• Radio Frequency Distribution Structure
• Aluminum Sheets
Conclusion
• Ultimate Stress of Steel:
• L – Brackets were installed to relieve stress

L-Bracket

Conclusion
• Surveillance Camera
• End Station A
Conclusion
• Radio Frequency Structure
