the negative strain denotes the compression side of the beam. I chose to say that negative strain is to the right and positive strain is to the left in order to match the deformed shape. Instead of arrows, it might be better to just think of strain values at each point along the section of the beam.

Can you do another video about the flexural strength formula as mention in ASTM C78 (concrete beam) because that's the reason why I came to this video. It says, Flexural Strength = (PxL) / bd³ Where, P is max pressure that works on beam till it fails, L: length of beam, b= base, d= depth. So PxL is Moment right? And what is bd³? Isn't it supposed to be Inertia (Ix) , which is 1/12 bd³?=M/Ix Why there's no 1/12 in that Formula? Thank you very much. And I hope you Understand my question because English is not my language. 🙏🙏🙏

Hi, while calculating how you determine Y should it be measured from top or bottom and why ? in case of symmetrical section its same thing whether you measure from top or bottom but in unsymmetrical section its not the same.

Why is it that Ɛ @ y isn't negative, but the maximum value of Ɛ [@ C] IS negative? If we're defining compressive strain as negative, why is the strain at y [which is above the N.A] not also negative? Thanks

Do you have a video that translates all of this into real-world implications, like wood and steel structure design or conceptual language. I'm thinking of something that discusses the material without using variables as a language? Rather than saying "Sigma is equal to E times Epsilon... Sigma divided by E... equal to minus y divided by c..." To some that sounds like a sentence, to others (myself) it sounds like a foreign language that I need translated without going to a huge variable glossary.
