Resultant of Three Forces and a Moment?

[Smijo]

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)?
