Question: Replace the force and couple-moment system by an equivalent resultant force and couple moment at point O. Express the results in Cartesian vector form. Units

Replace the force and couple-moment system by an equivalent resultant force and couple moment at point O. Express the results in Cartesian vector form.
Units Used:
kN = 103 N

Given:
F = (8 6 8) kN
M = (-20 -70 20) kN ∙ m
a = 3 m
b = 3 m e = 5 m
c = 4 m f = 6 m
d = 6 m g = 5 m
