Descrivi la tua esperienza lavorativa durante il tuo progetto di tesi
Tell me about yourself (they always start with this)
Stress strain curves, beam bending
what is the stiffness of this beamin which I would solve a problem.
Combination of basic statics, dynamics, material properties, and manufacturing technique questions, as well as brain teasers as mentioned previously.
You said that you are actually applying a master program of your major, whether you would still persue a master degree or choose to work if you get the full-time job at Apple?
Questions related to Solid Mechanics. 1. Describe 5 factors to avoid the deflection? 2. Attached a spring, what will be the force if the load applied is halved. 3. Where will be the point of break to the beam when a load is attached to the other free end.
1. Cantilever beam questions, how to improve stiffness of cantilever beam that holds apple logo in free end? name as many ways as you can. 2. Where the max deflection will happen? where point the stress is largest? 3. If you add extra stiffener, will you add it on top surface of the beam or bottom? 4. Which common injection molding defects you faced before? how you fix them? 5. four parts need to be made out from mold, where are the ideal positions for sprue, runner and gate? 6. which side should plastic inject from? core or cavity? 7. what's the difference between Cp and Cpk, which value indicates good tolerance control? 8. Name heat transfer modes. 9. Heat conduction question, know temperature, size, thermal conductivity of the heat source and thermal compound, calculate temperature on the other side. 10. Explain the definition of stress and strain?
