Age 5Explain it to a 5-year-oldStart with a picture

Imagine using Rotating Unbalance Force Amplitude to answer this question: calculate centrifugal force amplitude from rotating mass-eccentricity product and angular speed? Enter rotating mass-eccentricity product and angular speed; the calculator shows centrifugal force amplitude. For example: rotating mass-eccentricity product=0.024 and angular speed=180 produce centrifugal force amplitude=777.6. The answer tells you centrifugal force amplitude.

Age 15Explain it to a 15-year-oldConnect it to the formula

Ideal rotating-unbalance force amplitude is mass-eccentricity product multiplied by angular speed squared. This page evaluates the relationship directly. The rule is c=ab². Its input values are rotating mass-eccentricity product, angular speed, and the main result is centrifugal force amplitude. For example: rotating mass-eccentricity product=0.024 and angular speed=180 produce centrifugal force amplitude=777.6.

CollegeExplain it at college levelState the model precisely

This calculator evaluates the stated rotating unbalance force amplitude relation over the valid real-number domain stated below. The implemented relation is c=ab², evaluated from rotating mass-eccentricity product, angular speed to produce centrifugal force amplitude. Ideal rotating-unbalance force amplitude is mass-eccentricity product multiplied by angular speed squared. This page evaluates the relationship directly. Use radians per time; flexible rotors, speed variation, phase, distributed imbalance, support motion, and gyroscopic effects require fuller models.

Inputs and valid domain

  • rotating mass-eccentricity product must be a finite real number.
  • angular speed must be a finite real number.

Important boundary: Use radians per time; flexible rotors, speed variation, phase, distributed imbalance, support motion, and gyroscopic effects require fuller models.

The formula

c=ab²

How the calculator works through it

It substitutes rotating mass-eccentricity product, angular speed into the formula and exposes every numerical step above. The main output is centrifugal force amplitude.

Read the result correctly

The centrifugal force amplitude is the direct answer to “calculate centrifugal force amplitude from rotating mass-eccentricity product and angular speed.” Read it with the units shown beside the inputs; a sign, angle, percentage or rate changes what the number means.

A worked check

rotating mass-eccentricity product=0.024 and angular speed=180 produce centrifugal force amplitude=777.6.

Where this model stops being reliable

Use radians per time; flexible rotors, speed variation, phase, distributed imbalance, support motion, and gyroscopic effects require fuller models.

Learn it by changing one value

Begin with the worked example, then change one value while keeping the others fixed. Compare the new result and calculation steps to identify which part of the formula changed.
