May I ask how do you draw the BMD for the one-fixed-end-and-two-pinned-ends example? Just found that there are too many unknowns when I tried to solve it.
Hi Mike great vid. I'm a bit unsure about how you drew your bending moment diagram @ 3:18. Isn't the moment supposed to be zero at the roller support (point B)?
yo mo, ABC is one continuous beam (or a double continuous span) so that's why there is a moment about B. it's a statically indeterminate beam so there are redundant reactions. here is a link with some information about statically determinate vs indeterminate structures. www.quora.com/I-need-an-explanation-about-the-difference-between-statically-determinate-and-indeterminate-structures-And-which-is-more-applicable-in-real-life
After 25 years as a P.Eng., I finally understand why we can design based on plastic analysis.
This video is underrated. Should be booming in views like khan academy
great explanation too simple with the example
Thanks...that was very clear. I wish universities teach as well as you do :)
Thanks For videos...Please upload more example for plastic analysis
Woah!! Great video. Helping out with the lectures I'm going through. Looking forward to part 3?!?!?
Thanks! Yeah I'm hoping to upload the next part by the end of the week :-)

Sir, in under elastic moment the deflection would be a curve. why is the deflection profile linear in case of plastic moment?
It's a schematic diagram, not a cock...don't take it so literally...
