For the figure, what is the moment caused by the two forces F1 and Fall about a line starting at point P and extending to point Q? Use a Cartesian vector approach to solve this problem. Hint: It would be easier to find the resultant vector first, but it is not necessary Given: F1 F1= (2881 +691j -759 k) lb FAB = 2.7 kip • Point Q has coordinates of: (-0.250,3.750,-1.583) ft. A 4'-2" Note: In the US Customary (also...
