Hi Dstock, glad to see you still at least get your 1 post per day. Have you reviewed the 2016 and 2017 presentations by Bosch on direct? Pretty much similar materials especially your "blue dots" - lol As for statically indeterminate structures have you ever actually seen one in the field? - I have but only one as it was a very old rail bridge. Just curious do you know what is the name of the class required before the class on statically indeterminate structures? I do as I took that class first. How about which semester of calculus is required before either of the following structure classes - I took all of them. Keep on reading the papers from the national library of medicine but try to keep in mind they really do not all apply to nwbo as it appears you often believe
