Is the parallel component of moment always zero in a 3D plane?

I am making a program that asks the user to input a resultant moment (x,y,z) and resultant force(x,y,z). The program must calculate the parallel and

I am making a program that asks the user to input a resultant moment (x,y,z) and resultant force(x,y,z). The program must calculate the parallel and perpendicular moment using the given resultant force and moment.
