Today, Teri, Jabari, Scott, and I attended a tour of MTS Systems Corporation. Graduate students from civil engineering and students from the NEES REU also took the tour with us. The MTS employees who gave us the tour were very welcoming and enthusiastic when answering our questions. They showed us how some of their fatigue test systems and motion simulators work. Being a geology student, I was very interested in a rock mechanics machine that would use stress to identify rocks by their resistance.
