1. The problem statement, all variables and given/known data I have a picture attached with this static equilibrium problem. (Solve system for Fac and Fab) 2. Relevant equations Sum of x and y both=0 3. The attempt at a solution I just don't have a systematic easy approach to solving these systems. Does anyone have one? From the picture, they used the system of equations and add them together cancelling variables, but I don't know how exactly they did that. This class would be so much easier if I could do this well!!!
