Ql:- The coplanar force system shown in Figure below is subjected to a couple moment (M) and three forces. Two forces are known in magnitude and direction and shown in the Figure (150 N and 60 N). The third force is passing through the center of the semi-circle (point C). The resultant of all these forces is a single couple (750 N.m) counterclockwise. a) Determine the magnitude and direction of the third force. b) Determine the magnitude of moment (M). c) Replace the couple (M) by two vertical equal forces acting at D and E.
