    I cannot thank you enough. I've looked all over for a good explanation with no luck. This whole time I just needed 14 minutes of clear instructions for it to click. thank you thank you.

    hi, for ideal truss the connection shall be pinned , but in steel trusses practically some times the connection are welded with gusset plates , so a welded connection will remain a ideal truss connection or it will have some rigidity and moment?, please explain

    • @zunaidhassan9662
      @zunaidhassan9662 4 роки тому +3

      The 200# is in the positive x-axis and generates a clockwise moment which is negative.

    shouldn't it be -200(4.5) instead of -200(3) while writing the equation for M(a) ?

    • @balajihariharan7175
      @balajihariharan7175 4 роки тому +1

      no, its the shortest perpendicular distance, if u extend the LOA of the 200 force backward and then take the perpendicular distance from a it comes to 200(3)

    • @sweetpumpkin4586
      @sweetpumpkin4586 2 місяці тому

      I know this is 1 year ago, but for those who scroll by and have the same question. Its positive if you spin it counterclock wise and negative if the force moves clockwise im comparison to the pin.

    Thank you for the great video! I am just a little lost when it comes to decided whether to put + or - in these equations at the end. Can someone please explain how this works? Thanks in advance!

    • @timovalle3420
      @timovalle3420 2 роки тому +1

      Point A is a pin connection. Point B doesn't allow it to rotate clockwise so it must rotate counterclockwise. The forces acting upon pushing it clockwise are therefore negative. Point B (By) pushes it counterclockwise hence why it's positive.

    • @axxellblaze
      @axxellblaze 2 роки тому

      Oh thank you so much man. So does that mean the rotation is always going to the side the By is pointing to. Like it
      would be clockwise if the By is pointing down and counterclockwise if its pointing up(assuming that we have the same situation of course)

  • @KickenItOldSchool
    @KickenItOldSchool 4 роки тому

    You just said pins rotate so no moment then you use a moment equation at point A which is a pin. Could you please explain that?

    • @trexinvert
      @trexinvert 4 роки тому +1

      You are definitely very confused, so take a few steps back to review the basics.
      a.) True the pin connection creates zero reaction moment. (if it were "fixed", then yes it creates moment...then you must "add" a variable "Ma" to the FBD).
      b.) You can take a moment about any "arbitrary point" that you like. Typically, you take a point that can eliminate some variables. Thus, using "point A" as the reference point for your moment, then you "eliminate" variables Ax and Ay in your sum of the moment @ A =0 equation, since there is "no moment arm" for those forces.
      Hope this make sense and you can catch up.
