    Thank you! Im reading through a circuit analysis book and its difficult to stay focused, not the most exciting read but its fundamental stuff to be able to learn more interesting topics. I am glad videos like this exist it saves a bunch of reading!

      Lol wowwww, good detective work! I did record this one in the Netherlands 😂😂. I can barely even hear the siren on my headphones, let alone identify which country it's from. So good job haha 👏😁. I've actually recorded these videos in many countries, and trying to hide the background sounds is always a challenge! There are some exotic sounds throughout many of my videos 🤣

      dividing by 7 on both sides, so 7Va/7=8/7 basically Va =8/7 that is 1.143 v

  • @michaelmyers3507

      not nececary its because we assumed the Va to be smaller than 3v so we always subtract smaller from greater (correct me if im wrong)

    Why are you multiplying by 4 at 4:53?

    • @teamo8033
      @teamo8033 3 года назад +2

      Just to make the equation neater by removing the denominators. He multiplied both sides of the equal sign by 4, so the equation communicates the same information as it did before the multiplication. On the right side of the equal sign, 4*0=0.

      it means the polarity you assume is opposite of actual polarity, its stilla correct answer (correct me if im wrong)

  • @SXZLegionary
    @SXZLegionary Год назад

    I have a question. Why did you multiply everything by 4? I am looking through my class notes and on one of the examples they multiplied everything by 60 and another example by 120. I'm struggling to understand where those numbers came from.

    • @beet311
      @beet311 Год назад +1

      well you just multiply by whatever number to get rid of the fraction, in this case we get 4 from the denominator

    • @beet311
      @beet311 Год назад +1

      also whenever an equation is equal to zero we can multiply it and divide it by any number we want (except for 0)^

    At 3:26 why did you say the moment is anticlockwise when it's being rotated clockwise ruclips.net/video/smoPlJiLmac/видео.html

    • @Engineer4Free
      @Engineer4Free  3 года назад +6

      Counter clockwise is the positive sense for moments. F1 alone would cause the wrench to rotate clockwise about A, same with F2, and F4. All forces individually would cause a clockwise rotation. Notice how the moment caused by each force is a negative value? It just means that it's a moment with ___ magnitude, and the negative sign means it's going opposite the positive convention. A positive moment would mean the force tends to cause a counter clockwise rotation, but these are all negatives, and they all have the tendency to cause clockwise rotations, so hence their sign is negative. Hope that helps clear it up.

      He add the Va together as well as the -6 and - 2 together. Then after that he take the -8 which is the result of -6 and -2 to the other side which made it positive.
