Specification Clarification Questions

MESA does its best to ensure our specifications are as clear as possible. However, there are times during the Engineering Design Process rules need to be clarified. In those instances student participants may submit Specification Clarification Questions. Specification Clarification questions must be emailed to azmesa@arizona.edu. Questions should be discussed with MESA teachers prior to submission. Submitted questions should include your name, your school, and the MESA teacher should be copied on the email.

Question: The rules state that there must be a remote trigger. Does this mean no one can stand on the catapult to hold it down when launching?

Question: Can teams create digital models in platforms like Minecraft or Roblox?

  • Answer: Yes, digital models in platforms like Minecraft or Roblox is acceptable as long as the design meets all other specifications including scale for height, minimum height, designed to be located in Tucson or Phoenix, etc. Skyscrapers should also be realistic, some of the things that can be done within these platforms cannot be duplicated in the real world. Lastly, students should be prepared with a youtube or other video to demonstrate their model to judges as we cannot guarantee that students will be able to load these platforms on the computers at MESA Day.
