Homework Help: Force in each member of truss

  1. Mar 2, 2008 #1

    1. The problem statement, all variables and given/known data
    Determine the force in each member of the truss shown.


    2. Relevant equations
    [tex]\Sigma[/tex]Fx = 0
    [tex]\Sigma[/tex]Fy = 0
    [tex]\Sigma[/tex]M = 0


    3. The attempt at a solution
    I divided up the truss into different systems, the whole truss, and then a system for each pin. I must be doing something wrong because I found that FAP = 0 and FA = 0

    As far as the free body diagram, I wasn't sure about the force on the rollers, I just had a single horizontal force pointing inward for each and a force in the x and y directions for the pin at point B. Can someone give some direction?
    Thanks
