Forces Acting on Structures. Part 3

Professor Peter Plankton and Professor Tess Tube examine forces on structures. They specifically look at the impact of earthquakes and tornadoes. Footage from the recent earthquake and tsunami in Japan shows the devastating impact of these natural forces. Students will learn the difference between internal forces and external forces (live load vs. dead load); the various types of forces including compression and tension; materials and their properties and the environmental impact of these events.
