If you discovered a scratch in a pressure vessel what would you do? How would you solve this?
If you put a paper on top of a glass of water and turn it upside down, why does the paper stay attached to the glass?
Why I was interested in SpaceX.
1. Various technical structures questions (stress/strain, fracture, pressure vessels) 2. Basic fluids questions (pipe flow, Bernoulli, converging-diverging nozzles, choked flow) 3. Basic rocket propulsion (know the thrust equation) 4. Basic heat transfer (types, basic problems) 5. FEA/CFD analysis questions (how can you verify your solution is accurate - residuals, hand calcs, etc., how would you set up a fracture analysis in an FEA program, resolution of a boundary layer) 6. Questions about SpaceX (what are our engines and where are they used, what are our launch vehicles, what are our capsules, etc.) 7. For the first interview, some questions on PLM, SQL 8. Technical and non-technical questions about previous work/research experience - make sure you know what you did (obviously) and can explain it well. Be prepared for technical followup questions
Something about torquing bolts to 90%, how you expect different materials to deform due to this
In a sealed pressure vessel with gas, what happens when you raise temperature? How do you expect the tank to fail? What would the failure mode look like?

How are you doing today?
