The image above represents the centrifugal force. To calculate the centrifugal force, three essential parameters are needed and these parameters are the Mass of the body (m), the Angular Velocity of the body (w), and Radius (r).
The formula for calculating the centrifugal force:
F = mω²r
Where:
F = Centrifugal Force
m = mass of the body
ω = angular velocity
r = radius
Let’s solve an example;
Find the centrifugal force with mass of the body as 12, angular velocity as 32 and a radius of 8.
This implies that;
m = mass of the body = 12
ω = angular velocity = 32
r = radius = 8
F = mω²r
F = 12 x 32² x 8
Then, F = 12 x 1024 x 8
F = 98304
Therefore, the centrifugal force is 98304 N.
Calculating the Mass of the body (m) when the Centrifugal Force, Angular Velocity and Radius are Given
m = F / w2r
Where;
m = mass of the body
F = Centrifugal Force
ω = angular velocity
r = radius
Let’s solve an example;
Find the mass of a body when centrifugal force is 140 with an angular velocity of 24 and a radius of 10.
This implies that;
F = Centrifugal Force = 140
ω = angular velocity = 24
r = radius = 10
m = F / w2r
m = 140 / 24210
So, m = 140 / 576 x 10
m = 140 / 5760
m = 0.024
Therefore, the mass of the body is 0.024 kg.

Calculating the Angular Velocity (w) when the Centrifugal Force, Mass of the body (m) and Radius are Given
w = √F / mr
Where;
ω = angular velocity
m = mass of the body
F = Centrifugal Force
r = radius
Let’s solve an example;
Find the angular velocity when centrifugal force is 220 with a mass of the body of 14 and a radius of 6.
This implies that;
F = Centrifugal Force = 220
m = mass of the body = 14
r = radius = 6
w = √F / mr
w = √220 / 14 x 6
So, w = √220 / 84
w = √2.619
w = 1.618
Therefore, the angular velocity is 1.618.
Calculating the Radius (r) when the Centrifugal Force, Mass of the body (m) and Angular Velocity are Given
r = F / mw2
Where;
r = radius
F = Centrifugal Force
ω = angular velocity
m = mass of the body
Let’s solve an example;
Find the radius with a centrifugal force of 280, mass of the body is 16, and an angular velocity of 22.
This implies that;
F = Centrifugal Force = 280
ω = angular velocity = 22
m = mass of the body = 16
r = F / mw2
r = 280 / 16 x 222
Then, r = 280 / 16 x 44
r = 280 / 704
r = 0.397
Therefore, the radius is 0.397.
