Forces on Equilateral triangle truss

  1. Mar 18, 2012 #1
    Hey Guys,

    My question involves finding all of the forces acting upon each member. It is known that each side of the triangle has a length of l. It is also known that the force is acting at the very top of the triangle in the x direction (to the right) labelled as F.

    I found moments at both supports (bottom left + bottom right) to be (½)F. I have found that AD = F and for some reason AB = 0???

    Is this incorrect?

    How about showing the work you have done so we can see how you are thinking? That would help a lot.
