1. Resolve the force F into two components acting along the u and v axes and determine the magnitudes of the components. 2. Replace the three forces by a single equivalent force R (Le., resultant) and find its magnitude and direction angle e between R and the x-axis. Present Ras a Cartesian vector as well.
