Hi there, quick conceptual question just to make sure I know what I am doing...(adsbygoogle = window.adsbygoogle || []).push({});

I am given two forces, F1 and F2, in vector form with given magnitudes.

(I) Find the resultant force about point P (given).

(II) I am also asked to find the Moments of the resultant force about point P.

(I) I establish position vectors from P to each point (I'll call it A for F1 and B for F2) and multiply by magnitudes. Then add to get the resultant force about P.

(II) Then for the second part, I cross my resultant force about P with the "r" for the resultant force, which would be the distance between F1 and F2 from P?

It's that last sentence where you can see I'm unclear at. Any help would be greatly appreciated!
