Centrifugal Force Equations and Calculator
Centrifugal Force - When a body of mass rotates about an axis it exerts an outward radial force called centrifugal force upon the axis or any arm or cord from the axis that restrains it from moving in a straight (tangential) line.
In the following. equations:
F = Wv2 / gR
F = centrifugal force in lbs or kg
If n = number of revolutions per second
F = 1227WRn2
W = FRg / v2
v = [FRg / W]1/2
R = Wv2 / Fg
n = [ 2933 F / WR ] 1/2
F = centrifugal force in pounds
Note: If a body rotates about its own center of mass, R equals zero and v equals zero. This means that the resultant of the centrifugal forces of all the elements of the body is equal to zero or, in other words, no centrifugal force is exerted on the axis of rotation. The centrifugal force of any part or element of such a body is found by the equations given below, where R is the radius to the center of gravity of the part or element. In a flywheel rim, R is the mean radius of the rim because it is the radius to the center of gravity of a thin radial section.
For SI Units:
F = Mv2 / R
F = centrifugal force in Newtons
