Webinar Unit 1 – Natural Frequencies

We held our first Shock & Vibration Webinar on January 17, 2014. This presentation was sponsored by the NASA Engineering and Safety Center, to which I express gratitude.

A link to the audio/visual recording will be posted here in the near future.

In addition, here are some files from the January 17, 24 and 31 webinars.
