Hi, thank you for your videos. I have a question, why do we not include Bx as a reaction? I thought it was a pin. Is it a weightless link then? Thank you in advance!
Hello, if we look at the figure the at B there is a link attached to it. So similarly to what we did for the link CD, we disconnect this link at B and replacing it with a force that is in the line of action of the link. In this case this link was totally vertical and that's why only By is included. I hope this clarifies your question!
Hello Marcel, sadly I will be really busy this last part of Fall2021 semester. But you could guide yourself by one of my shear and bending diagrams videos: 1 - th-cam.com/video/elnwOEDfLIk/w-d-xo.html&ab_channel=LearningbyTeaching 2 - th-cam.com/video/l_khO0MLGKQ/w-d-xo.html&ab_channel=LearningbyTeaching 3 - th-cam.com/video/KvpedXCsPh4/w-d-xo.html&ab_channel=LearningbyTeaching 4 - th-cam.com/video/fgJgnMECQzc/w-d-xo.html&ab_channel=LearningbyTeaching
Why are you neglecting to include the vertical component forces at C and D in the free body diagrams? Why are you zeroing the component forces at these points. Despite it not asking for them they still exist and can't exactly be ignored.
Thank you for this very informative video!

The pin at B is two force member right? Like in CD THAT'S Why you worte the reaction is By
hi, how would you do the shear diagram and bending moment for this exercise?

@@LearningbyTeaching Perfect! Thanks for the help
Good
why not component for Cy and Dy
Why we did not calculate the shear forces for point c?
Hi, the question did not ask for the forces at point C. :)
@@LearningbyTeachingShouldnt there be shear forces when internal forces are exposed even if it's not being asked?

Hi , isn't point B pin conectd that means there's Bx and By right? So where is Bx
Thanks alot.
no need. there is no horizontal forces
The whole class is currently copying from this
Too small to see
Hello, thanks for the comment. I will try to write bigger for following problems!
