3. Problem Statement
• Construct a self-starting and
stopping transportation vehicle using
supplied materials in discovery box.
The vehicle shall not exceed the
dimensions of 16”x5”x8” and must
transport five (5) steel balls weighing
a total of 335 grams, twenty (20) feet
ending in a 9” diameter target area.
4. Design Criteria
1.Dimensions: 16’’L x 5”H x 8”W in
stored position
2.The vehicle must transport cargo
twenty feet
3.The vehicle must start and stop
under its own power
4.Discovery Box or the 1201 Store
materials only can be used to
construct the vehicle
5.Total Cost: Less than $15.00
5. Research Findings
Overweight Permit Fee.
• In North Carolina, there is an annual fee of $100 per vehicle or $200 per
vehicle if it is a mobile home. ¹
Weight limit for interstate highways is 40 tons.
• One 40-ton truck does as much damage to the road as 9,600 cars. ²
Damage Caused to Roadway Due to Overweight Loads
• “One of the problems with heavy loads is that extra weight has an
exponential effect on the road's surface.” ³
• Haulers are constantly increasing the size of load to the trucks maximum
capacity. This makes it a hazard to the community. ⁴
Gear Ratio and Weigh
• Increased Drive Ratios result in higher torque ⁵

25 Seconds\nWelcome all to Group 4 of XLIX Engineering design firms Innovation presentation\nIntroduce:\nProject, Team, Name, Major\n
30 sec\n“Todays presentation will highlight the different areas of our project, we began with an introduction of our team and members. Then we will talk about the projects focus through the problem statement. The project had some very specific design criteria, which we will bring to your attention. As we began our project we first directed pulmonary research and then conducted engineering calculations to better understand the solutions available. We used a decision matrix to choose our final project direction and determined a projected and final cost. Our end product will then be introduced and analyzed before opening for questions and comments.”\n
25 Seconds\nThis is the problem statement we developed based on the teams decision to transport the simulated overweight load….(Read)\n
25 seconds\nThese design criteria were put into place by xlix engineering design firm, and we had to consider and adhere to them when developing our final product.\n
60 seconds\nThese were the research findings we found most interesting, mainly focusing on the damage that overweight freight loads cause to the interstate and road systems in our country. Also we determined our gear ratio due to the research we conducted\n
15 seconds\nThe three engineering calculations we focused on were in an effort to determine optimum motor output to transport the load and also the required amount of string spool needed to engage the break once the load reached the destination at 20 feet.\n

45 seconds\nFirst we calculated the circumference of the wheels in order to determine the number of revolutions needed to travel 20 feet. Next we determined the circumference of the axle we would use as a spool in order to engage our breaking system. After we found the number of revolution of the wheel and axle assembly we multiplied that number with the diameter of the axle and determined we would need 10” of string to spool in order to stop within the target.\n

15 seconds\nHere are the more detailed engineering calculations\nAs you can see here we needed to add an additional 2” of string to our projected break system due to the trajectory of our transporter \n
30 seconds\nWe built a decision matrix to analyze the alternatives we found most important. We considered 4 different drive options including gear drive, propeller drive, friction motor drive, and rubber band drive\nFor construction materials we considered both the foam core and basswood\nAs for wheels we were deciding between the 3” yellow wheels and the 4 ¾” red wheels\nBased on the matrix the most viable options were the gear drive, basswood construction, with the 3” yellow wheels\n

30 seconds\nWe chose the gear drive motor due to its predictability, consistency, and simplicity\nThe wheel choice was based on its size(gear use), strength/stability(contact area, deflection resistance), and design unity(axle fit)\nThe design matrix showed we should use basswood construction, however due to limited tooling, we choose to use the foam board because of its ease of use. Weight wise is provided nearly the same advantages as basswood, and offered the dimensions we required for construction.\n

25 seconds\nThis is the final design of our cargo transporter\nRails, bamboo skewers\nfor adjusting axel (parallel)\nfor glue less attachment to axels/vehicle\nBinder clips = not modifiable\nSmall Binder Clips\nAxel placed through metal loops, 4pt pressure axel\nprovided smooth movement of axels\nAllowed for use with multiple axel types (wood/metal)\nMetal axels\nprovide smooth movement\nVery strong, with overweight cargo\n
10 seconds\nAs you can tell by our final bill of materials we came in well below our $15.00 budget, beating it by nearly 35%. Without sacrificing build quality or purpose\n
15 seconds\nOur team was able to successfully complete our problem statement within the restrictions of the design criteria\n(Read)\n
5 seconds\nAt this time we would like to open the presentation and invite any questions or comments about our project or results….\n
