    Every other video or textbook just goes on explaining how to calculate BM or SF but none of them explain what exactly is happening inside the beam
    I am a masters student and I found this video helpful.
    Cheers!!!

    • @MichelvanBiezen
      @MichelvanBiezen  ปีที่แล้ว +2

      Great! Yes this concept is a mind bender as it appears to contradict what we have learned about forces and the moment.

      @@MichelvanBiezen I can't thank you enough for putting this content out, I wish I was more fiscal to say thanks that way.
      But your help is often the difference between giving up with this study (which often feels overwhelming) and carrying on.
      I've tested myself as a visual, kinetic learner and I'm studying at home with 100's of pages of dry text book reading to do, and I say I'll do 10 pages a day, but then hit a brick wall of not getting something or I'll spend an hour on one page alone. So although you put this out 7 yrs ago, take comfort in the fact, you're still helping people today and you'll be helping people probably long after you leave this mortal coil. That's pretty cool.
      Edit I'm getting to the point where I'm trying to watch, take notes from your video series before I do the text book reading, just so I can visualise it better. So again thank you so much.

    On a simply supported beam BM is max at centre and zero at support so does that mean we have maxm strain at centre section and zero at support?

    • @skepticmoderate5790
      @skepticmoderate5790 4 ปีที่แล้ว

      These are the reaction forces. They oppose the bending of the beam.

  • @tome6023
    @tome6023 4 ปีที่แล้ว

    So positive moments are moments that OPPOSE, react against the bending/deformation of the beam?

    • @MichelvanBiezen

      This video is specifically covering BENDING moments of the beam and that is how they are defined.

    • @MichelvanBiezen
      @MichelvanBiezen  6 ปีที่แล้ว +1

      As explained in the video the moments are considered positive by convention as they are caused by the internal forces of the beam.

  • @qpla3653
    @qpla3653 4 ปีที่แล้ว

    If this internal moments action oppose to bending of the beam, how beam bend?? Plz explain sir...

    • @MichelvanBiezen
      @MichelvanBiezen  4 ปีที่แล้ว

      Opposing the bending does not mean that the beam doesn't mean the beam doesn't bend at all , but that it will bend less.
