1. The problem statement, all variables and given/known data Two forces P and Q are applied as shown to the corners A and B of a square plate. Determine their magnitudes P and Q and the angle (weird B) knowing that their resultant R has a magnitude R = 120 N and a line of action passing through O and forming an angle of 30 degeres with the x axis. 2. Relevant equations 3. The attempt at a solution (R = 120 N @ 30 degrees) = sqrt ( (Px+Qx)^2 + (Py+Qy)^2) ) I could go further on that but know that somehow a moment is involved here and don't know how to place it. Thanks.
