(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

2. Relevant equations

ƩMoments = Moment + Fx*d + Fy*d

R = (Fx)i + (Fy)j

3. 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.
