Resolve F_1 into components along the u and v axes and determine the magnitudes of these components.

#### Solution:

### Let us first draw the vector components as follows:

### Now, let us draw the vectors tail to tail as follows:

### Now, we can use the Sine law to figure out F_{1v} and F_{1u}. (Forgot the Sine Law?)

### \frac{F_{1v}}{\sin30^0}=\frac{250}{\sin105^0}

### F_{1v}=129N

Simplified solution excellent
