3D Equilibrium

  1. Nov 2, 2008 #1
    3D Equilibrium(and Moments)

    1. The problem statement, all variables and given/known data


    2. Relevant equations

    Sum of the forces in x=0
    Sum of the forces in y=0
    Sum of the forces in z=0
    Sum of Moments (at a point) =0 (of x,y,z)

    3. The attempt at a solution

    Since it is a fixed end there is 6 unknowns right at the origin (Ax, Ay, Az, Max, May, Maz). It also states that the the force is parallel to the XY plane so I take it there is no k component of the force. The only problem I am having is with the force it says "its magnitude will not exceed 970N". I tried breaking up the 970N into i and j components using the coordinates given and calculating the moment about the origin using cross product, but I got the wrong answer. I know how to solve the problem, but the force is throwing me off.

    Any hints would be nice, thanks!

    Anyone have any ideas? Sorry for the rush, but this question is killing me.
