help with cables? - fatalfairie7 - 04-27-2014 11:21 PM Two snowcats tow a housing unit to a new location at McMurdo Base, Antarctica, as shown in Figure 4-46. The sum of the forces FA and FB exerted on the unit by the horizontal cables is parallel to the line L, and FA = 3300 N. Determine FB and the magnitude of FA + FB. http://www.webassign.net/giancoli/4-46fig.gif FB_____N FA + FB_____N - Naman - 04-27-2014 11:25 PM FB = 5016 FA+FB =6456 - wildyoungnfree - 04-27-2014 11:30 PM FA=3300 N FA component parallel to L = 3300 Cos 50 = 2121 N FB = 2121/ cos 30 = 2449 N FA + FB = 3300 + 2449 = 5749 N |
