1. The problem statement, all variables and given/known data Three forces: F1, F2 and the other with a magnitude of 40 N act on the ring bolt as shown in Fig. C.1. The resultant, R, has a magnitude of R = 180 N and acts at an angle of 80° anti-clockwise from the x-axis. Determine the magnitudes of F1 and F2. 2. Relevant equations ƩFx ƩFy 3. The attempt at a solution ƩFx=F2*cos(40)-F1cos(60)=180*cos(80) ƩFy=F1*sin(40)+40+F2*sin(40)=18-*sin(80) ????????
