This system can only be understood if we first understand equilibrium. An entity is considered to be in equilibrium if it has all forces exerted equally. If all forces exerted upon an entity are equal, they cancel each other, making the impact 0.
The term “concurrent forces” refers to forces that meet while passing through a common place element. You can combine concurrent forces to create vectors. This gives you the final result. It is important that you know that acceleration is zero in equilibrium.
Equilibrium Types
There are two main types of equilibrium for concurrent forces. These are static equilibrium and dynamic equilibrium . These two types of equilibrium for concurrent forces have different implications. Let’s take a look at the different types of equilibrium for concurrent forces.
Dynamic Equilibrium
Dynamic equilibrium is a state in which the outcome of concurrent forces is null but velocity is not. A stone sitting on a table can be considered to be in static equilibrium. Dynamic equilibrium can also be achieved by attaching a stone to a thread. It is still moving even if the net force of the stone attached to the string is zero. This is the simplest method to determine the style of dynamic equilibrium for concurrent forces.
Static Equilibrium
Static equilibrium refers to a state in which all forces and accelerations are equal to zero. Both acceleration and velocity are zero.
Coplanar Forces
Coplanar forces are forces that act in the same plane. Under certain conditions, coplanar forces may also be in equilibrium.
* To be considered coplanar forces, the sum of all forces must equal zero
* The summation of all moments of forces at an instance on the clockwise route is equal to the summation of moments of forces at the same instance on the anticlockwise route.
It is vital to remember that there are many types of coplanar forces. Concurrent coplanar forces of equilibrium require that the forces in one plane intersect at a common point. It can be calculated by using both algebraic and graphical techniques.
Non-concurrent and parallel coplanar force are two other types of coplanar force. Non-concurrent coplanar force vectors are those that do not intersect at any point, and they don’t even have to be parallel. Parallel coplanar forces are forces that exert force in a parallel manner on an entity.
We hope you now have a better understanding of the different states of equilibrium and concurrent forces.
Here’s an interesting fact about the equilibrium of concurrent forces
You can explain the idea of equilibrium between concurrent forces using Newton’s first and second laws of motion.
