## How to Calculate Wheel Speed | Sciencing

In terms of linear motion, speed is defined as the distance traveled divided by the time taken. Bodies that rotate, such as wheels, use a different quantity to define rate of rotation. This is often the number of revolutions carried out per minute. It is straightforward to convert between revolutions per minute and linear speed.

A grinding wheel is a uniform cylinder with a radius of 8.5cm and a mass of 0.580kg. Calculate (a) its moment of inertia about its center, and (b) the applied torque needed to accelerate it from rest to 1500rpm in 5.00s if it is known to slow down from 1500rpm to rest in 55.0s.

## Grinding Wheel Safety: Respect The Maximum Speed

In short, never over-speed a grinding wheel. The speed of the grinder must be compared to the speed marked on the wheel or package to make sure the machine’s speed is at or below the maximum operating speed of the wheel. Surpassing this rating risks not just wheel breakage but also the safety of shop personnel.

## Question about a rotating wheel? Angular velocity etc

RPM is the number of revolutions in one minute. RPM is therefore a particular angular velocity (as some clever bod pointed out: only applicable to rotating objects). Degrees per second or radians per hour would be other angular velocities (and as the clever bod pointed out this could refer to any object moving in a curve).
