Homework Help: 3D Equilibrium of 4-wheel support

  1. May 31, 2016 #1
    1. The problem statement, all variables and given/known data
    The plate has a dimension of 460mm X 260mm, subjected to a central load of 400N.
    Determine the reaction A and B, each representing a roller support as a wheel, located at the center of one edge. (opposite blue arrows have the same resultant value.)
    Are they the same ? If not how can I find them out ?

    2. Relevant equations
    N/A

    3. The attempt at a solution
    I did both force and moment summation giving me A+B=200.
    I am sorry if this seems like a kindergarten problem.

    What did you take as rotation axes ?
