Structural Theory | Castigliano's Second Theorem (Beam Deflection) Part 1 of 3

[@AJ-et3vf]

Thank you so much sir for this great lucid lecture about Castigliano's theorem using a simply supported beam with overhang as an example. I always struggled to get the correct answer for the deflection and slope when the beam is not a cantilevered one, such as simply supported beams. I don't know how the support reactions will contribute to the deflection at the point of interest. So this is really very useful to me. Thank you so much sir

Very well-explained, thank you! Took me off guard when you added the deflections, but now it makes sense you are looking at the deflection at the end of the beam.

Thanks from Brazil 🇧🇷

Thanks man, well explained!

[@emelinewayne3575]

very helpful, thank you so much sir.

Thank you! It’s soo much clearer now! 😅

where did 4p get it from?

[@champion7179]

How to find the deflection between B-C, I mean 3/2 m

[@janineduannepelayo1991]

pano po nakuha yung 4p/3? sa may summation of moment at A po :)

[@fitrahmayulu5690]

4 p dapar dari mana?

[@nurinaina1650]

may i ask, what is R? like in RAY and RBY i knoe the ay and by but R?

[@adrienjoshua6710]

It's the same. R is just for "reaction".
