Determine the couple moment. Use a vector analysis and express the result as a Cartesian vector.

M = (800i-4800j-800k) lb-ft
M = (4000i-2000j+4000k) lb-ft
M = (-4000i+7000j-4000k) lb-ft
M = (-800i-4800j-800k) lb-ft

M= Ubc (dot) Rab x Fb.
Ubc= (1/9) <3,-6,-6>

F=600

Ubc (dot) F = <200,-400,-400>
Rab= <-4,-12,-2>
M= <4000,-2000,4000>
M= (4000i-2000j+4000k) N-m.
