SOLVE ASAPThe line of action of force F₁ = 388 N is passing through point A(+2,+3,+1) towards B(+5,+5, +4), while that of force F₂ = 488 N is through point C(+3,+1,−1) towards D(-2, -3, -4). Use a right-handed coordinate system.a. Determine the moment of force F₁ about the origin.b. Determine the moment of force F2 about the origin. c. Determine the magnitude of the resultant moment of forces Fi and F₂ about segment OE. Point O is the origin and point E is at (+5,+5,-3).

The 10-N force is applied to the handle of the hydraulic control valve as shown. Calculate the moment of this force about point O. as shown in .the fig 20° F = 10 N 250 mm B' | 60° 37.5 mm

If F1=(140i+-150j+95k)kN, and F2=(-230i+280j+80k)kN, determine the resultant moment produced by these forces about point O. Express the result as a Cartesian Vector (Fill Mx, then My, then Mz). ( don't forget to put the sign for each component) My is 4m My is F2 Mz is 3m
