Problem Statment

Design a cart that is safe, resilient, low-cost, low-weight, and user-friendly. The cart will be resilient by being strong and durable that can perform in multiple environments, extreme temperatures, absorbs impact and safely clears the ground. It will be user friendly by having free spinning wheels and will have a safe and efficient way to slow down and stop the cart. It will be light weight enough to be easily lifted, transported and collapsible. It will be safe enough for the riders, the dogs, and the bystanders. It will be single operant and be able to hold 2 average-weight people while being able to travel at speeds up to 30 mph.

Decision Making


Over the Spring break, the team met to make further decisions on the urban mushing cart. The following are possible options that we have narrowed down for the use of our chassis.
  • Square vs. Round Tubing
    • Thickness of material
  • 4130 Alloy Steel (Chromoly) vs. 606-T6 Aluminum
Pros:
  • Easier to weld

Cons:
  • Load concentration areas

Pros:
  • Cheap
  • Widely Available

Cons:
  • Harder to weld/bend
Future tasks

  • Budget
    • The team also spoke about funding for the cost of the material. The budget is currently $1000, but in the case that budget will be exceeded the team has determine that fundraising will be a necessity. The team has contacted fundraising coordinators at Warner Brothers Studios to attend TV show tapings in the event that more funds are needed.
  • CAD
    • A few things that the team will be working on in the following weeks is create rough CAD designs in order to get an idea of what materials will be more advantages. This task will also assist in determining what material and shape we should use when our CAD designs undergo static analysis.
