(1) If θ = 30° and T = 6 kN, determine the magnitude of the resultant force acting on the eyebolt and its direction measured clockwise from the positive x axis.
(2) The truck is to be towed using two ropes. Determine the magnitudes of forces FA and FB acting on each rope in order to develop a resultant force of 950 N directed along the positive x axis. Set θ = 50°.
(3) If Φ = 45°, F1 = 5 kN, and the resultant force is 6 kN directed along the positive y axis, determine the required magnitude of F2 and its direction θ.
(4) If θ = 30° and FZ = 6 kN, determine the magnitude of the resultant force acting on the plate and its direction measured clockwise from the positive x axis.
(5) If the magnitude of the resultant force acting on the bracket is to be 450 N directed along the positive u axis, determine the magnitude of F1 and its direction Φ.
