ƩMoments = Moment + Fx*d + Fy*d
R = (Fx)i + (Fy)j
The Attempt at a Solution
I'm only interested in part (ii)
I calculated the components of the resultant force and they are
|R| = 1.15(i) + 9.36(j)
I know that the x-intercept of line of action is sum of moments divided by R(j) and y-intercept is sum of moments divided by R(i). I'm given a point A where the line of action goes through but I'm not quite sure how to use that bit of information to find M.
Any help is appreciated.
