SUMMARY

To build an efficient mouse trap car capable of traveling over 175 feet, utilize the provided materials, including 4 CDs for wheels, 1/4" brass axles, and a small mouse trap (4.5 x 10 cm). Key strategies include ensuring the axles are well lubricated and securely assembled to minimize friction and maximize distance. The design must adhere to the specifications of traveling in a straight line without modifying the mouse trap itself. Additional materials may be incorporated to enhance performance.

PREREQUISITES
  • Understanding of basic physics principles related to motion and friction
  • Familiarity with engineering design processes
  • Knowledge of material properties, particularly for balsa wood and rubber
  • Experience with assembly techniques for mechanical projects
NEXT STEPS
  • Research effective lubrication methods for axles to reduce friction
  • Explore aerodynamic design principles to enhance straight-line travel
  • Investigate the impact of weight distribution on vehicle performance
  • Learn about tension mechanics to optimize the use of the mouse trap's spring mechanism
USEFUL FOR

High school engineering students, hobbyists interested in mechanical design, and educators looking for hands-on project ideas in physics and engineering.

Hey everyone, My name is Brandon and I have been assigned a mouse trap car project for my high school engineering class.

Homework Statement



The following are the specs:
-I need it to go the maximum distance
-Must travel in a straight line
The materials supplied:
-4 ea. CD's (wheels)
-2 ea. 1/4" brass axles
-4 ea. 1/4" beveled rubber washers
-4 ea. 1/4" flast rubber washers
-4 ea. 1/4" flat steel washers
-2 ea. Balsaa wood chassis rails, 36" long max.
-1 ea. 1/8" x 3" x 12" balsa deck
-1 ea. 1/8" x 12" brass tube
-1 Small mouse trap (4.5 x 10 centimeters)
-1 Small zip tie
-Fishing line cut to any length

Homework Equations


My concern is figuring out how to build the most efficient mouse trap car to go upwards of 175 feet. In addition I am allowed to use my own materials but the ones listed above must be used. Also, the mouse trap it self can NOT be modified. Does anyone have any suggestions?

I did one when i was in SEA (Science and engineering academy) camp a few summers back. I found that if you keep the axels well lubricated and sturdy, it would be a good start. just make sure you get all of the pieces put to gether as well as you can and don't cut corners. that's the best i got, but nobody else seems to be helping
