(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The directions of the two thrust vectors of an aircraft can be independently changed from the conventional forward direction within limits. For the thrust configuration shown, determine the equivalent force-couple system at point O. Then replace this force-couple system by a single force and specify the point on the x-axis through which the line of action this resultant passes. These results are vital to assessing design performance.

3. The attempt at a solution

I found the resultant force from the two thrust vectors

Fx = T + Tcos15

Fy = Tsin15

R = Fx + Fy = T*2.225

but after this I'm stuck on what to do, am i supposed to find the moment or set this equal to the moment?
