    Rpm Wheel
In summary, the conversation is about finding an equation to determine the RPM of a wheel. The suggested method is to divide the time it takes for the wheel to spin around once by 60. The term "RPM" stands for revolutions per minute.

Hello,

I am a programmer and I would need an equation to determine the RPM of a wheel.
  1. First I select a point in the wheel.
  2. Then I measure the time it takes for the wheel to spin arround once.
  3. This would give me the results.
What would be a good equation for this?

Just divide that into 60.

Do you know what "RPM" stands for? It basically tells you the equation.

Related to Good equation for calculating RPM of a wheel?

1. What is the formula for calculating RPM of a wheel?

The formula for calculating RPM (revolutions per minute) of a wheel is: RPM = (60 x v) / (2πr), where v is the linear speed of the wheel and r is the radius of the wheel.

2. How do I measure the linear speed of a wheel?

The linear speed of a wheel can be measured by dividing the distance traveled by the wheel by the time it takes to travel that distance. This can be done by using a speedometer or by using a stopwatch to time the wheel's rotations.

3. Can this formula be used for any type of wheel?

Yes, this formula can be used for any type of wheel as long as the linear speed is measured in the same units as the radius (e.g. meters per second and meters).

4. Does this formula take into account the wheel's mass or other factors?

No, this formula only takes into account the linear speed and radius of the wheel. Other factors such as the wheel's mass and air resistance may affect the actual RPM of the wheel.

5. Can this formula be used to calculate RPM for non-circular wheels?

No, this formula only applies to circular wheels. For non-circular wheels, a different formula or method must be used to calculate RPM.
