How to use the Rotating Rim Speed Calculator
Use the radius of the specific point of interest, not the full wheel diameter. All points share angular speed but their tangential speeds vary with radius.
The calculation
Worked example
At 0.1 m radius and 60 rpm, tangential speed is about 0.6283 m/s and centripetal acceleration 3.9478 m/s².
Assumptions and limits
Ideal rigid steady rotation. The calculation does not evaluate material stress, imbalance or safe operating speed.
