how can the equilibrant of two or more concurrent forces be found

Find the net force of the two concurrent forces, and then reverse the direction of the net force. There's your equilibriant.

SIMPLE ex: 2N east
Equilibriant: 2N west

The equilibrant of two or more concurrent forces can be found by following these steps:

1. Understand the concept: Concurrent forces are forces that act on the same point or object, but in different directions. The equilibrant is the force that can balance out the effects of all the other forces, resulting in a state of equilibrium.

2. Identify the concurrent forces: Determine the magnitude and direction of each force acting on the object. Make sure to represent these forces as vectors with appropriate magnitude and direction.

3. Find the resultant force: Calculate the resultant force by adding all the concurrent forces using vector addition. This involves adding the force vectors tip-to-tail, with the direction and magnitude taken into account.

4. Determine the equilibrant: The equilibrant is a force that has the same magnitude as the resultant force but acts in the opposite direction. To find the equilibrant, simply reverse the direction of the resultant force.

5. Verify equilibrium: If the equilibrant force is applied to the object, it will balance out the effects of all the other concurrent forces, resulting in a state of equilibrium. The object will have zero net force and no acceleration.

Note: You can use graphical methods, such as constructing vector diagrams, or algebraic methods, using trigonometry and vector components, to find the resultant force and the equilibrant. It depends on the complexity and nature of the concurrent forces involved.
