Triangular plate, Virtual Work

  1. Jun 27, 2010 #1
    1. The problem statement, all variables and given/known data

    The triangular plate weighs 80N, is articulated to the bars AH and EF (negligible weight) through joints in the points H and D respectively.
    Determine the horizontal reaction at support A using the principle of virtual work.
    Problem image here: http://imagepaste.nullnetwork.net/viewimage.php?id=1087 [Broken]

    2. Relevant equations
    Work=0=Sum Force*Displacement + Sum Moments* d Theta


    3. The attempt at a solution
    Try to find the displacements, but I want to know the quickest way for solve this problem.
    Any recommendation on how to solve this problem more efficiently, be grateful.

    Thanks
