Hello! I am cruising through the videos/flashcards on my way to my 4th PDD attempt (yippee) and am wondering why there isn’t much info on Black Spectacles on the actual structural calculations? I definitely have been tripped up on the exam(s) by a few of them and would like to have a refresher and some practice before heading back in there. No doubt I probably over-complicated a simple question, but even having that explained would be tremendous.
Thanks!
