## Homework Statement

I will post a photo of the question in the thread once I've created it. I have found the magnitude and angle of the resultant force, but I am unsure of how to proceed. I find moments and couples confusing.

## Homework Equations

$$\vec M = \vec r \times \vec F$$

## The Attempt at a Solution

So, to find ##\vec r## I chose a point on ##\vec F## (1, 0.8069) (call it C), and calculated ##r_{BC}##: ##r_{c} = -7i + 0.8069j##. Then I took the cross product of r and F, and got 41.58kN.m, but this is incorrect, and I am stumped.
