Thanks for the help but I'm still a little stuck. I can work out the magnitudes fine but I'm a bit confused as to where the negatives should be and what they actually represent. This is my working so far (the joints are labelled A-K from left to right):
Fab = Force along member AB
Consider...
Can someone please help me start this question, I missed some vital notes in class and don't know how to do it. I just need to know the method so I can go on to do it myself Thanks :)
