The Attempt at a Solution
Well we need to finding F1x F1y and F2x F2y.
I found Fx already by doing:
F1x=51000cos30
F1x=44167.3N
F2x=68000cos60
F2x=34000N
So Fx= F1x+f2x
Fx=78167.3 N
But I don't know how to find Fy and the direction, but I know I need fy first before I find the direction. I know for Fy you use the sin instead of cos but I don't know how to find Fy.. need some help please.
thanks!
