Example Calculation

Example: Centrifugal force on a carousel
Problem:

A child with a mass of 30 kg sits on a chain carousel. The distance to the axis of rotation is 5 m and the orbital velocity is 8 m/s. What is the centrifugal force?

Given:
  • Mass m = 30 kg
  • Radius r = 5 m
  • Velocity v = 8 m/s
  • Find: Centrifugal force F
Solution:

\(F = \frac{m × v²}{ r}\)

\[F = \frac{30 kg × 8²}{5 m} \]

\[F = \frac{30 × 64}{5}\]

\[F = 384 N\]

Practical Applications
Automotive engineering: Cornering, tire grip, rollover safety
Mechanical engineering: Unbalance calculation, centrifuges, washing machines
Amusement parks: Carousels, roller coasters, rides

Formulas for centrifugal force

The centrifugal force is an inertial force that occurs during rotational and circular motion. It is directed radially outward from the axis of rotation. The unit of measurement is Newton (N).

The basic formula for centrifugal force in circular motion.

\[\displaystyle F_Z=\frac{m \cdot v^2}{r}\]
Mass in kilogram (kg)

Rearrangement of the basic formula to calculate mass.

\[\displaystyle m=\frac{F_Z \cdot r}{v^2}\]
Orbital velocity in m/s

Calculation of velocity with known force and radius.

\[\displaystyle v=\sqrt{\frac{F_Z \cdot r}{m}}\]
Radius in meter (m)

Calculation of radius with known force and velocity.

\[\displaystyle r=\frac{m \cdot v^2}{F_Z}\]
Important Notes
  • The centrifugal force is a fictitious force (inertial force)
  • It only acts in rotating reference frames
  • The force is proportional to the square of the velocity
  • At double velocity, the centrifugal force quadruples
