Final Design Final concept is a fusion of previous ideas. Final concept is a fusion of previous ideas. Angled side supports are used to add stability to the design. Angled side supports are used to add stability to the design. Crossbars are moved in order to adjust the height of the rails. Crossbars are moved in order to adjust the height of the rails.

Final Concept: Primary Components Crossbar: Main Support:

Final Concept: Primary Components Breaking Support: Side Arm:

Assembly Assemble the Main Base Supports Assemble the Side Angled Supports

Assembly Add Crossbars to the Main Base Supports Add Side Angled Supports

Assembly Connect the Main Rails to the Crossbars using the insert Repeat the steps above and add to the first part

Assembly Final Assembled View

Calculations: Main Rail Weight: Less that 150 lbs, the max weight as set by sponsor Less that 150 lbs, the max weight as set by sponsor 90 lbs should be easy to move and handle 90 lbs should be easy to move and handle

Calculations: Main Rail Bending Stress: The total stress in the beam is less than the yield stress The total stress in the beam is less than the yield stress Gives a Factor of Safety of 2.4 Gives a Factor of Safety of 2.4 This shows that the main rail will support the total weight of the test cart This shows that the main rail will support the total weight of the test cart

Calculations: Main Rail Deflection: Rail bends downward with most weight expected Rail bends downward with most weight expected Displacement approximately 1/8 inch Displacement approximately 1/8 inch Some deflection expected, 1/8 inch small enough to be tolerated Some deflection expected, 1/8 inch small enough to be tolerated

Problems and Solutions Design Design Cost/Budget Cost/Budget Order stalled due to financial difficulties Order stalled due to financial difficulties Storage of material Storage of material Transportation of material Transportation of material Machining Machining Assembly Assembly

Final Accomplishments Easier assembly: Easier assembly: Simple collar-pin design; minimum tools Reduced assembly time: Reduced assembly time: one section: ~5min 34sec full track: ~22hrs Smaller assembly team: Smaller assembly team: three people Mobility: Mobility: all part weigh less than 150 lbs Height and terrain adjustable Height and terrain adjustable
