Early Tuesday morning we went to visit Mr. Duke's senior physics class at Davidson High School. Mr. Duke's students do the classic physics bridge building activity. Using our bridge breaker device, a 50-pound metal and wood pressing machine, the students measured the strength of their bridges. They were also able to collect data, both video and numerical, that can be analyzed later. The strongest bridges broke when crushed by more than 300 lbs of force.
