**What is the resultant force?**

A resultant force is defined as a total force acting on the body along with their directions.

On the other words, it is the single force obtained by combining a system of forces acting on a rigid body and it has the same effect on the rigid body as the original system of forces.

The resultant force may be determined by the following laws :

**Parallelogram law of forces :**

**By this law, two forces acting simultaneously on a particle and it can be represented in magnitude and direction by two adjacent sides of a parallelogram, then their results may be represented in magnitude and direction by the diagonal of a parallelogram which passes through their point of intersection.**

Similar kind of application applicable for triangle, polygon and for similar types of another shape.

**Resultant of two or more intersecting forces found :**

Where two or more intersecting forces are found then for solving resultant of that forces steps given below :

Step -1: First of all resolving all the horizontal forces

Step -2: Then resolving vertical forces

Step - 3: Then put all data in the below equation and equate.

Step - 4: Answer will be the resultant force that what we find.

**R = √ ( ∑horizontal force )**

^{2}+ ( ∑vertical force )^{2}
A number of force acting on a particle will be called in equilibrium when :

**∑ horizontal force = 0**

**∑ vertical force = 0**

**Resultant force for the two forces that are not parallel or any kind of forces :**

Step - 1: Draw a free-body diagram of the object.

Step - 2: Draw coordinate axes on the free-body diagram.

Step -3: Decompose the forces acting on the object into x and y components.

Step - 4: Calculate the x and y component of the resultant force by adding the x and y components of all forces.

Step - 5: Find the magnitude and direction of the resultant force by using x and y component.

**Notes :**

If the resultant force acting on a stationary object is zero, the object will remain stationary.

If the resultant force acting on a moving object is zero, the object will carry on moving at the same speed in the same direction.
