    Doing a question. Brain is fried. Don't understand the attached answer.

    My working for the last subsystem, the couple. \underline{G} = 0 \times \underline {F} + 0' \times -\underline{F} = (0 - 0') \times \underline{F} = \overrightarrow{0'0} \times \underline{F}.

    Why is it \overrightarrow{00'} \times \underline{F} instead of what I've got?

    Just considering the couple created by the last two forces, then I agree, it should be \overrightarrow{0'0} \times \underline{F}

    I don't know why you've equated it to \underline{G} though, based on what's posted.
