Chapter 4, Problem 35P

(II) Two snowcats in Antarctica are towing a housing unit to a new location, as shown in Fig. 4–38. The sum of the forces ${\stackrel{\to }{F}}_{\text{A}}$ and ${\stackrel{\to }{F}}_{\text{B}}$ exerted on the unit by the horizontal cables is parallel to the line L, and F_A = 4500 N. Determine F_B and the magnitude of ${\stackrel{\to }{F}}_{\text{A}}+{\stackrel{\to }{F}}_{\text{B}}$.
