Question

Describe the resolution of forces

Answer 1

Your answer:-

It is defined as the process of splitting up the given force into a number of components , without changing its effect on the body is called resolution of a force.

A force is usually resolved into two components that are perpendicular to each other.

A force can be resolved into two component forces graphically or by using trigonometry.

Consider the diagram above. In the diagram the force F is resolved into two perpendicular component forces that is the Fy and Fx components (using parallelogram method).

To calculate the magnitude of the vertical (Fy) and horizontal (Fx) forces, we can use simple trigonometry.

Fx = F cos θ , Since cos θ = (Fx/F)

Fy = F sin θ, Since sin θ = (Fy/ F)

Examples of calculation:

By using the diagram above, Let say F = 80 N and θ = 30 degree

The horizontal component Fx,

= F cos θ

= 80 cos 30

= 80 X 0.866

= 69.3 N to the right

The vertical component Fy,

= F sin θ

= 80 sin 30

= 80 x 0.5

= 40 N upwards
