Analysis of structure

  1. Jul 12, 2007 #1
    If the loads are all vertical in a truss, will there be horizontal component on the hinge of the given truss?
    Does the presence of the horizontal component depends on the design of the truss?

    What hinge? Could you give us a diagram...?

    Usually there is a later component in a truss, or a diagonal element. However, I would expect some lateral element because structures are 3-D.

    Yes - I would have thought that was pretty obvious looking at the diagram.
    Consider taking moments about point C.

    Just to echo what mgb_phys mentioned, you should be able to visualize the forces at A in your mind. If you were to pull down at that point, can you not convince yourself that the member AB will not pull diagonally on point A?

    Thanks - I was worried that I sounded a bit condescending - then I noticed the cornel.edu address and figured this wasn't a grade4 student!
