Resultant of Three Forces and a Moment?

  1. Jul 7, 2014 #1
    I'm looking to find the resultant force of three forces and a moment: Fx, Fy, Fz, and Mx. I intend to graph multiple resultants.

    Would I just need to do the following to find the magnitude?

    Sqrt(((Fx+Mx)^2)+Fy^2+Fz^2)




    Thanks

    You will need to sum the forces and moments separately.

    Your expression is OK for the magnitude of the force --- if the moment is removed.

    Sum them separately as in...

    sqrt(Fx^2+Mx^2+Fy^2+Fz^2)
    or
    sqrt(Fx^2+Fy^2+Fz^2) and sqrt(Mx^2)?
