Engineering Mechanics: Force couple

[Dfresh]

Homework Statement

Problem is:
Replace the 150-N force with an equivalent force-couple system at A
Since it is really hard to describe the scenario in words, attached is a link that shows the diagram of the question.

Homework Equations

Cross Product and sum of forces

The Attempt at a Solution

So I have the feeling I screwed up somewhere. What I did was I first converted the force into its components, producing me with -150cos35j+150sin35k. Since one of the things that the question asked was for I just simply took -150cos35 and 150sin35. I then decided to find the D which yields me (-0.1m)i+(0.12m)j+(-0.2m)k. Since the moment is equal to FxD, I took the cross product of these two values to produce me a value of (14.25N m)i+(-8.6N m)j +(-12.29N m)k. I have the strange feeling it is wrong and I screwed up somewhere. Can anyone help me with the problem?

Check the direction of the components of the force. Look at the coordinate axes to make sure the components are oriented in the correct sense.

Ah I see now! Thanks!
