    How to Determine the Equivalent Forces-Couple System at Point O?

    how could i solve this question? Three forces acting in the XY-plane are applied to a body. F1= i + 3j applied at (2,5) F2= 3i - 3j applied at (0,11) F3= i + 12j applied at (5,-4) (a) Show that the moments of F1 and F1 about the point P(3,8) are both zero. (b) Find the moment of F3 about P...
