Hi everyone, i came across this forum a while ago and have been lurking here for a while. Any ways, i have a simple problem but cant seem to find a solution to it the photo of the problem is the link just here http://i1053.photobucket.com/albums/s463/Popa911/1cc85138.jpg 1. The problem statement, all variables and given/known data Three cables exert a force on a bracket (as shown in the photo) F1=300N, F2=500N and the resultant is 400N and 30° downward from x. 2. Relevant equations the equation i used to solve was Fr=F1+F2+F3 rearranged to get F3= Fr - F1 - F2 3. The attempt at a solution I got the i and j components and put them together as follows. F3= (346.41i -200j) - (180i + 240j) - (500i) F3 = -334i - 440j this answer is incorrect as it would mean that cable F3 is going through the wall? Any help would be appreciated, thanks.
