(4) The two structural members, one of which is in 3 kN tension and the other in compression, exert the indicated forces on joint O. Determine the magnitude of the resultant R of the two forces and the angle 0 which the resultant vector makes with the +x-axis. Ans: R = 3.80 kN, 0=-21.6° (or 338°) 3 30° 2 kN
