Extracted text: Given are 4 points in space: (x,y,z) A (3,2,3) B (0,1,4) C(2,4,1) D(0,5,4) The line of action of force vector F passes from point A to point B and has a magnitude of 20 kN. The line of action of force vector G passes from point C to point D and has a magnitude of 35 kN. 1. What is the summation of forces along the z-axis? 2.What is the magnitude of the resultant force of force vectors F and G? Express your answer in unit of kN. 3. What is the resultant of the moment caused by force vectors F and G about the origin? Express your answer in unit of kN-m
