    Expressing resultant force in unit vectors i and j

    Hi thanks for the reply, I understand that if I move 2.5kN to the 2m mark, I will get a clockwise moment of 6.25kNm. However the question asks me to "Express my answer using the unit vectors i and j" How would I express 6.25kNm into its appropriate unit vectors?

    Expressing resultant force in unit vectors i and j

    Homework Statement The question is fairly easy, however the way they want the answer displayed is doing my head in.. Anyways the questions states "replace the loading system by an equivalent resultant force (express your answer in terms of the unit vectors i and j)" The question is a...
