23. 

Determine the magnitudes of the resultant force and its direction measured from the positive x axis.

[A]. R = 12.49 kN, = 43.9° CW
[B]. R = 13.6 kN, = 21.5° CW
[C]. R = 14.00 kN, = 60.0° CW
[D]. R = 10.80 kN, = 68.2° CW

Answer: Option A

Fx=+4+10sin(30)=9.
Fy=-10cos(30)=-8.66.
R= in square root sum of Fx square and Fy square=12.48.
