The magnitude ofthe forces' In the ropes are F15~ 1.156 kN, F2 - —75 lb, and F3: 60 lb. The (x, y,z) locations of points A, B and C are: Point A (3 ft, 12 ft, 0) t ‘ Point 8 (O, O, 4 ft) Point C (O, 12 ft, 4 ft) a) Determine the resultant force vector]? , where R is equivalent to the three forces shown. Express R in terms of vector components. b) Determine the coordinates of the point where the line of action of R intersects the yz—p/ane. dybérwlgfl41‘2ml: ttz; / b) Foowflwlr: WZ’Vf’”: \M“ "f”:‘llamémfl p—fi—é €3,19er Y2“ Wm: Afifimmfbowi ‘ f’UaM r: RWC‘OG 2 9 .
