1. The problem statement, all variables and given/known data Also, im not entirely sure what the question is exactly asking. Also, what does the line of action represent? 2. Relevant equations M = Fx(Perpendicular distance) + Fy(Perpendicular distance) For couples: M=Fd 3. The attempt at a solution i was thinking that i need to find the moment at D, but wouldn't the resultant force still be the same? except located at D? However, since this is a couple, would the moment be the same everywhere?
