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!
