A 4m long beam is subjected to force and moment loadings. Replace the loading with an equivalent force couple system at end A of beam.

Replace the loading system by an equivalent resultant force and couple moment acting at point A. Assume F1= 45 N, F2= 30 N and F3= 55 N.

A machine component is subjected to the forces shown in the figure, each of which is parallel to a co-ordinate axis. What is the equivalent force-couple system about point A?
