Two locomotives on opposite banks of river pull a vessel moving parallel to the banks by means of two horizontal ropes. The tension in these ropes are 280 lb force (F1) and 380 lb force (F2), while the angle between them is 70°. Find the resultant pull on the vessel and the angle between each of the ropes (θ1 and θ2) and the sides of the canal

Consider the steel column of a single storey building with the system of parallel forces as shown in the Fig. Determine the magnitude of FA and FB such that the resultant force passes through origin O of the given column. Use only vector approach to solve the unknowns given.
