I DO NOT WANT THE SOLUTON JUST PLS EXPLAN WHY WE DO NOT CONSDER THE WEGHT OF MEMBER AC??

EXAMPLE 1 200 KN 3 m SON sor A 2-D force system with geometry as shown. Determine the equivalent resultant force and couple moment acting at A. And then the equivalent single force location measured from A. 100KN Plan: 1) Sum all the x and y components of the forces to find FRA' 2) Find and sum all the moments resulting from moving each force component to A. 3) Shift FRA to a distance d such that d = MRA FRY /
