Stress analysis of the trailer complete!
We recently completed the stress analysis of our trailer and are excited to announce that our design does not fail when subjected to loads greater than 200 lbs. This not only provides for an excellent factor of safety, but means we can now purchase our materials and soon get manufacturing started!

CAD drawings complete
We are excited to announce that our CAD drawings are complete!
You can see that our trailer is going to look great after it is cut, bent, machined, welded, painted, and put together!

More Features Finalized
When choosing a material for our trailer we first considered our maximum load requirement, followed by our weight requirement, followed by material availability and cost analysis.
With the second to highest yield strength, lowest density (and therefore product weight), and low price point, we chose the 6061 T6 Aluminum Alloy which also happens to be extremely available partially because of the aircraft industry.
We got together and finalized the trailers dimensions. These dimensions are made to carry a large load while still retaining the agility to safley navigate on single track trails as well as bike lanes. Our dimensions are: 63" Length x 19.5" Width x 16" Height with a clearance of 6" from the ground.
We also looked in to power generation. Our options include rotational energy, solar energy, and possibly the use of miniature wind turbines for wind energy. More on power generation to come soon!
Lastly, we recently found shock absorbers for our trailer and put in an order for two. They should arrive soon!
| Material | Yield Strength (psi) | Density (lbs/in^3) | Price 1ft length, 0.083 wall thickness, 1.25 inch O.D. | For 20ft |
| 6061 T6 Aluminum Alloy | 40,000 | 0.0975 | $15.21 | $304.20 |
| 304 Stainless Steel | 25,000 | 0.288 | $32.33 | $646.60 |
| 316 Stainless Steel (Super Corrosion Resistant) | 30,000 | 0.288 | $31.00 | $620.00 |
| 4130 Cromoly Alloy Steel (Easy Weld) | 65,000 | 0.284 | $11.53 | $230.60 |

Update #2 - Sketches from Matt
After all of our meetings with Matt, we finally have sketches depicting a good conceptual view of our trailer.
Matt did a great job depicting our many ideas in his sketches.
