G'day.

I have a problem with my statics work, i understand its probably quite simple but I am having trouble in my understanding.

Essentially problems make more sense to me by using the component method, although in saying that i understand this problem would be quite a lot more simple were i to approach it without the component method.

heres the vector diagram for the problem,
this is the answer for the sum of the components, but I am confused why Fx is negative and why Fy is being multiplied by 3+3cos45, i understand the barebones equation for the moment is M=fd(perpendicular), but from my understanding Fx would be acting in the positive (right) direction.
