The interview was difficult for me because I was not ready to ask some of the technical questions. That said, the questions weren't unreasonable.

The interviewer seemed uninterested in any of my work experience, even though it was related to the job. He seemed to want more personal/extracurricular activities.

I asked what type of person makes a good intern, and he practically replied verbatim with what I had previously said I did not have experience in. This seemed jarring and unnecessarily harsh, considering the interviewer knew I was a student. He could have said literally anything else.

Given a simple mechanical structure, what are the forces acting on it? Where are the moments? What are the internal loads?
