All the three concurrent forces acting on a body will not produce equilibrium.
The given parameters:
<em>1. 1 N, 3 N and 5 N</em>
<em>2. 2N, 2N and 2 N</em>
<em>3. 3N, 4N and 5 N</em>
<em>4. 4N, 4N and 5 N</em>
Concurrent forces lie on the same plane and their line of action pass through a common point.
A body under concurrent forces is in equilibrium if the resultant of the forces on the body is zero.
where;
is the equilibrant force
First set of concurrent forces;
Second set of concurrent forces;
Third set of concurrent forces;
Fourth set of concurrent forces;
Thus, we can conclude that all the three concurrent forces acting on a body will not produce equilibrium.

Answer:
See the answers below.
Explanation:
to solve this problem we must make a free body diagram, with the forces acting on the metal rod.
i)
The center of gravity of the rod is concentrated in half the distance, that is, from the end of the bar to the center there is 40 [cm]. This can be seen in the attached free body diagram.
We have only two equilibrium equations, a summation of forces on the Y-axis equal to zero, and a summation of moments on any point equal to zero.
For the summation of forces we will take the forces upwards as positive and the negative forces downwards.
ΣF = 0
Now we perform a sum of moments equal to zero around the point of attachment of the string with the metal bar. Let's take as a positive the moment of the force that rotates the metal bar counterclockwise.
ii) In the free body diagram we can see that the force acts at 18 [cm] of the string.
ΣM = 0
B would be an example of vaporization (liquid to gas).
———————
A is an example of deposition (gas to solid); C is an example of condensation (gas to liquid); and D is an example of condensation, deposition, or freezing—depending on the type of cloud.
