What is Reddit's opinion of Vibration Analysis for Electronic Equipment, 3rd Edition?

From 3.5 billion Reddit comments

It is a fun field. While I would poke at myself for 'just' making boxes that hold the important stuff, getting to work closely with electrical engineers on thermal management and RF/structure interactions was rewarding. I can also brag I have fixed software errors in hardware now.

I would recommend a book I have not read yet, but have had on my list for a long time: Vibration Analysis For electronic equipment. https://www.amazon.com/gp/product/047137685X/ref=ox_sc_saved_title_8?smid=A2SFH68ZG8QDCF&psc=1

Vibration Analysis for Electronic Equipment covers different shape PCBs and PCBs supported by points, IIRC. Irregular shapes are not covered - I suspect because a lot of these random vibration models were derived experimentally.
