An object's equilibrium state can be categorized based on the force systems acting on it. They are collinear, coplanar concurrent, and coplanar non-concurrent forces.

Consider two individuals exerting equal and opposite forces while pulling a rope. The two forces acting on the rope are collinear such that the net force on the rope is zero. The system is in equilibrium.

In a coplanar concurrent force system, all the forces meet at a single point on the same plane.

Here, these forces can be resolved into their horizontal and vertical components.

For a system to remain in equilibrium, the upward and downward vertical forces must balance. Similarly, the leftward and rightward horizontal forces must also be equal and oppositely directed.

In a coplanar non-concurrent force system, the forces acting on the object are parallel. Here, the moment due to F₃ is clockwise and is balanced by an anticlockwise moment due to F₂.

Similarly, F₁ is counterbalanced by the object's weight and the net moment and the net force on the object are zero, maintaining the equilibrium.
