Resultant and Moment

    Convert the system of forces to an equivalent single resultant force and a corresponding couple at C. Find the projection of the couple at C along a line adjoining DE. Sketch the system.

    2. Equations related.
    Fr = F[tex]_{1}[/tex] + F[tex]_{2}[/tex] + F[tex]_{3}[/tex]
    M = r x F

    3. Attempt at the problem.
    Is this correct?
    Fy = F[tex]_{3}[/tex] - F[tex]_{1}[/tex]
    Fx = 0
    Fz = F[tex]_{2}[/tex]

    Then find Fr = [tex]\sqrt{Fy^{2} + Fx^{2} + Fz^{2}}[/tex]

    M = r x F.

    So does that mean I draw a perpendicular line from C to the line of D and E.
