Industry Consultant Interaction Summary

Date	Consultant(s)	What We Talked About
April 17, 2026	Steve 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, 2026	Chiyo 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, 2026	Sarah 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.
