Computer Simulation
• Modeling– Computer Aided Design
• 3D part drawings were constructed• Parts were then assembled as required
– Finite Elemental Analysis• Stress analysis was performed on the original
design and the new designs proposed• Maximum principal stress was compared for each
design

Packaging
• Procured Boxes, bubble wrap, and tape
• Provide Client with 2 options– Option A
• Smaller box therefore cheaper shipping cost• Much more assembly required
– Option B• Larger box therefore more expensive to ship• Less Assembly required
