Simple statics (or Physics) question..... I summing forces in the x, and y, directions and finding that forces directed in the positive y, and negative x directions (quadrant II), have positive y values, but all the solutions (chegg and the back of my textbook are showing the forces in the y-direction as negative when they are in quadrant two. Can you please look at the attached problem I did and tell me what concept I have wrong?
