    Part a) moment = Force x perpendicular distance so F1 = 3x3 = 9nm
    F2 = 12 x 3 = 36nm
    F3 = 3 x 22 = 66nm
    F4 = 3 x 23 = 69nm

    part b) F1 anticlockwise
    F2 Anticlockwise
    F3 Clockwise
    F4 Clockwise

    part c) Resultant moment = total clockwise moments - total clockwise moments
    = (F3 + F4) - (F1 + F2)
    = 135 - 46
    = 89nm clockwise

    I would suggest you write the unit for moment of force as N m. In physics, nm represents nanometre or nanometer.

    Sorry I am late to the party, but it seems that the question has been answered correctly. The only thing missing is the explanation behind it. This 6 min video will explain it and give other examples:-
