Centrifugal G Force Formula
The following equation is used to calculate the Centrifugal G Force.
Fgc = [ V^2 / r ] / G
- Where Fgc is the number of g-forces of acceleration seen by the rotating object
- V is the tangential velocity of the object (m/s)
- r is the radius of rotation (m)
- G is the acceleration due to gravity = 9.81 m/s^2
What is a Centrifugal G Force?
Definition:
A centrifugal G-force measures the acceleration seen by a rotating object relative to the acceleration due to gravity. In other words, it’s the object’s acceleration divided by the acceleration due to gravity.
How to Calculate Centrifugal G Force?
Example Problem:
The following example outlines the steps and information needed to calculate the Centrifugal G Force.
First, determine the tangential velocity of the object. In this example problem, this is measured to be 50 m/s.
Next, determine the radius of the rotation. This is measured to be 3m.
Finally, calculate the number of G-forces using the formula above:
Fgc = [ V^2 / r ] / G
Fgc = [ 50^2 / 3 ] / 9.81
Fgc = 84 .95 Gs
