How does the free body diagram work in these problems? I do not understand how we can make a cut between A and B, and the only force we write is F_ab. Also, what about the force R_e? This is the part of these problems that I do not understand well…
Do you mean specifically for statically indeterminate problems? For combined deformations, castigliano's theorem is probably what you're looking for: ruclips.net/video/oJU94i-O19U/видео.html , but for just combined stresses, yes, you usually have both, actually: ruclips.net/video/Fp5-jjmaksM/видео.html . For a more general combined loading situation, not specific to shafts, you can check my other videos on Mohr's Circle, for example.
This video and all the accompanying ones are simply brilliant! So well formatted and clearly explained. I really learned the concept. Thank you!
Saved my life thanks

same here my brain gives error when it comes to show reaction forces
shouldn't it be 46.3 mm and not micro?
Can you do bending and torsion on a shaft até the same time

@@LessBoringLectures Thank you, i'm having trouble calculating diameters for shafts under bending and torsion where fatigue doesn't apply
