Answer:
The result is an unbalanced force to the right or acting in the a-axis.
Explanation:
For the first diagram, we propose a sum of forces on the X & y axes and include these forces arithmetically, i.e. the upward forces with a positive sign and the downward forces with a negative sign. Forces to the right with positive sign and forces to the left with negative sign.
ΣFx = 0
+ 1 +3 = Fx
Fx = 4 [N] (units of Newtons]
ΣFy = 0
-2 + 2 = Fy
Fy = 0
Therefore the result is an unbalanced force to the right or acting in the a-axis.
