Answer:
0
Step-by-step explanation:
Force AC resolves to 2 N in the AB direction and 2 N in the BC direction. Directions AB and CD are opposite, as are directions BC and DA. So, the sum of forces in the AB direction is ...
AB -CD +part of AC = 1 -3 +2 = 0
The sum of forces in the BC direction is ...
BC -DA +part of AC = 2 -4 +2 = 0
The resultant of these 5 forces is 0. There is no net force in any direction.
