Hopefully if we can get some notes also 🙂

I dont have notes unfortunately but in the future I will be posting questions and answers

@@Stubbornnut Did you post Q&A - will learn alot with that info. Please let us know where it is posted. Thank you

Nice job! Question, why are you utilizing in/sec for pk vue?

[@Stubbornnut]

it’s peak velocity.

[@themoochman111]

@@Stubbornnut Yes, I am aware; should not be in/sec for peak vue - Acceleration/g's is utilized for impact/friction at high frequency detection. Was wondering why it was displayed during lecture, no big deal.

[@Stubbornnut]

what i meant is that what you are seeing isn’t peak vue. it’s peak velocity. basic spectrum. not peak vue.

@@Stubbornnut ok starting at (~) 31:43 the slides say pk vue at top of screen & is referenced as such, but Velocity/in/sec is being used for data, which is incorrect set up. Always Acceleration/gs. Yes, it's a great idea to compare standard spectrum taken with velocity/ips or even displacement/mils to Pk vue or HFD for early detection, pk vues main purpose & its sensitivity/ contrasts. It may have been some plots mistakenly placed in slide show. Hard to keep track, I instructed as well.
