Moment about a point in an incline plane

  1. Oct 9, 2016 #1
    1. The problem statement, all variables and given/known data


    Force F = 460 N acts perpendicular to the inclined plane

    Determine the moment produced by F about point A.
    Enter the x, y, and z components of the moment separated by commas.
    2. Relevant equations

    3. The attempt at a solution



    u(CA) x u(CB)=1.28i+.36j+.48k

    r(CA) x F=1382i-1767j-2356k

    masteringengineering.com says the answer is wrong. Please help!
