    His teaching of the technical elements is amazing...period! but we can't discount how his humour and relaxed personality keeps us engaged so we allow ourselves to learn. I've never met any teacher, instructor or prof like Dr. Hanson. This guy is beyond the real deal.

    I'm studying through UNISA, which is a self study from home with no tutor.. Making sense of this without a tutor is a nightmare but you sir are a proper legend!!! Other videos I've come across skip so many steps and I end up more confused.. I saw this 1 hour long video and almost shat myself.. I just need to tell you that this was probably the most valuable hour I have ever spent!! Thank you for the wonderful tutorial and amazing breakdown explaining absolutely every step along the way. You get people that are paid to teach and people that CAN teach and this is your calling!

    Dr. Hanson, you've helped me in so many classes. I thought I was doomed because I passed solids and Statics and you didn't have any videos past those subjects. Until I got to analysis of structures and we had to do beam deflection again. 1 hour of you explaining the process and im like a pro again. Thank you for helping me become an engineer.

    If I have a beam with loads in the middle and free ends. Do I have to make cuts at the free ends?

  • @1light4love
    @1light4love Před rokem +1

    Mann thank god for you and going this grinder with us, Prof! 😵‍💫🤓I spent a solid t hrs on one of these with a partial distributed load (same supports) in my last HW today….. I feel way better watching this- except now I know I need to triple check my math/reductions along the way. And shoot maybe I’ll plug it into the smaller v equation and see if that gets me the answer in the back….
    I’m confused though, after finding the equation from A to B (across the beam) we were asked to solve for the deflection at A,B and the midway (C). Why wouldn’t the deflection at A and B be zero though? Isn’t that what our boundary conditions State for these pins and rollers??🤔

    just by using first 2 boundary conditions we can solve it right ? in that case c2 and c4=0 in fact your c4 is almost zero c4=(11/128 pl^3)=almost (1pl^3/12)
    do we need to use 4 boundary conditions?

  • @zm479
    @zm479 Před 3 lety

    For the second M(x) equation, could you have set the right side of the beam as the origin and derived an equation that way? Or is it necessary to have the same origin for both equations?

    • @keepmahaney7412
      @keepmahaney7412 Před 2 lety

      I’m pretty sure that it is necessary because our “x” variable must represent a distance from the same point. If you did set the right side of the beam as the origin, then your value of x would represent the distance from point “B”. X in both equations of M(x) needs to represent distance from point “A”.

    Jeff kind of messed up at about 17.30 minutes of the video. It'd be better to write the equation for a slope at a point like dy/dx = 1/EI * integral(M(x), dx) for easier understanding...

    Greetings from Poland Mr. Hanson. We have a little bit different signs, for example your V it is our R (reaction), but methode is the same. I wish I want to have teachers like you in my University.
    P.S.
    In my University I didn't pass exam, because in task like that, my constanses of integration were written in the end of eqation, not in 1 interwal. In profesor's opinion it wasn't agree with ,,art of counting in Clebsh methode"

  • @wademax5009
    @wademax5009 Před 3 lety +2

    I agree that the slope absolute value would be about the same on either side of c, but wouldn't the values of the actual slope be equal and opposite on each side? Ex.) One will be concave up and one will be concave down ?

    • @abu-bakr9604
      @abu-bakr9604 Před 3 lety

      No they would be equal but not opposite signs because his coordinates for both his cuts are all in the positive x axis. So the slopes will be both equal and positive.

      When you set the two equations equal to each other EI cancels each other. For example (1/EI)b = (1/EI)c . Find c?

I mean it’s fixed and the slope in fixed conditions are zero. But you side slope is not zero in point A PLEASE I HAVE A FINAL IN FEW HOURS HELPPPP
