Homework Help: Very Easy Truss Problem

  1. Nov 27, 2013 #1
    1. The problem statement, all variables and given/known data

    For the bridge shown in the diagram, find the components of the reaction force at A.


    2. Relevant equations

    sum of force = 0

    3. The attempt at a solution

    sum of force y = 0 = Ay+by-F=0

    Moment at B = 0 =-Ay*4 +F*3

    therefore Ay = 3F/4

    and Ax =0 (roller)
