Industry Consultant Interaction Summary

DateConsultant(s)What We Talked About
April 17, 2026Steve Brooks
Brian Nasralla
  • Steve urged the importance of understanding how to communicate effectively with one another.
  • Steve also said that opportunities beyond internships are critical for a Mechanical Engineer, including clubs, volunteering, and personal projects.
  • Brian told us that repeatability in design is important.
  • Vibrations and movements in the chassis are important to minimize.
  • Considering the surface where our design will be tested should be factored into our design.
  • The chassis should remain stable for predictable and consistent launches.
April 24, 2026Chiyo Miyaki
Benjamin Gove
  • Tolerance for chamber and piston.
  • Ways to minimize friction between the two pieces.
  • How to ensure a consistent, guided path while minimizing friction.
  • Discussed minimizing unnecessary shear forces and moments in our design.
  • Showed them the broken piston piece.
  • How to add more force to achieve launch distance without compromising our structure.
May 8, 2026Sarah Brown
  • Force-body diagrams: how can we mitigate the horizontal force from the piston launch?
  • Add friction/rigidity to the base.
  • Discussed weight distribution.
  • Discussed varying stroke length and whether we can generate enough force.
  • Looked into ways we could reduce print/manufacturing times.
  • Good ideas, but we must make sure we have time to test them and ensure they work.
  • Is our design potentially too overengineered?
  • Looked into ways we could simplify our design.
