For the attached figure, what is the moment caused by the two forces F1 and FAR about a line starting at point P and extending to point Q? Use a Cartesian vector approach to solve this problem. Given: F1= (400i + 800j - 600k) Ib FAB = 1.5 kips Point Q has coordinates of: (-1.333,4,-2.5) ft. Note: In the US Customary (also known as English) system of units, we often write lengths as shown below. Note that 4'-2" is said as, "4 feet, 2 inches" and is equal to 4*12 + 2 = 50". It is not 4 feet minus 2 inches. F1 A 4'-2" P FAB 3'-4" 7-'6 l'-0" 2'-3"
