Calculate the moment of the force about point O.
MO = (3(0) - 4(0))i - (2(0) - 4(200))j + (2(0) - 3(200))k = 0i + 800j - 600k Calculate the moment of the force about point O
rOA = 2i + 3j + 4k
F1x = 100 cos(30°) = 86.60 N F1y = 100 sin(30°) = 50 N F2x = 150 cos(60°) = 75 N F2y = 150 sin(60°) = 129.90 N Calculate the moment of the force about point O
