More Fun with Stobe Lights

I posted an earlier video showing falling water visualized using a strobe light. Here's another video showing three whiffle golf balls connected with rubber bands and the three modes of vibration, again captured using a strobe light.

And finally, a very entertaining video showing a structure created in finite element analysis software ANSYS, with the modes of vibration animated. What's great about this example is that most 3D parametric modelers (Inventor, Pro/Engineer, SolidWorks, etc) have either built in capability to do similar analysis or can do so through an add-in. This would be a great way to get students involved in promoting your program - have students create their own little videos showing various structures and their modes of vibration. Competition in the classroom is always a great motivator.
