A 12 inch grinding wheel has a surface speed of a mile a minute. What is its revolutions per minute?
A wheel with a diameter of 12 inches will have an angular speed of 560.2 revs per minute.
Surface speed of an eight inch diameter wheel at 2000 revolutions per minute?
The circumference of an 8-inch diameter wheel = d*pi = 8*pi. Each revolution will advance the wheel by one circumference, so 2000 revolutions per minute would be 2000 * 8 * pi = 1600pi feet per minute.
A Ferris wheel has a radius of 25 feet The wheel is rotating a 2 revolutions per minute Find the linear speed in feet per minute of the seat on this Ferris wheel?
1 revolution = 2PI radian. 2 revolutions = 4PI radian The angular speed of the Ferris wheel is 4PI radians . Multiply by the radius. The linear speed is 100PI feet per minute.
How do you find surface speed and rpm cylindrical grinding?
The speeds for grinding are not measured in RPMs. They are measured by peripheral wheel speed in surface feet per minute.Ê
Do the surface types on an inclined plane affect the speed of a hot wheel on an inclined plane?

At how many revolutions per minute do the wheels of a bike typically spin?
The revolutions per minute of a bike wheel depends on the size of the wheel, the speed you are riding, and other factors. It is generally thought it can spin at 2 revolutions per second.
How speed increases by pressing accelerator?
Pressing on the accelerator increases engine rpm (revolutions per minute) which in turn increases wheel/tire rpm which increases vehicle speed.

What is the speed of a 20 ft wheel turning at 2100 RPM?
About 2997.279 MPH. (IF your taking a 20' RADIUS.) If you are talking of a 20' diameter. then would be feet/minute = rpm * diameter * pi 131946.891468 feet/minute
A wheel on a vehicle has a diameter of 36 inches If the vehicle is moving at a speed of 50 mph how many full revolutions will the wheel make in one minute?
1760 yards = 1 mile. 60 minutes = 1 hour. 36 inches = 1 yard. 50*1760 divided by 60 = 1466 yards 2 feet in one minute Circumference of wheel = pi*36 = 113.0973355 inches 113.0973355/36 = 3.141592654 yards 1466.666666/3.14192654 = 466.8048878 revolutions in one minute So the wheel makes 466 full revolutions in one minute.
