The speed of the abrasive wheel is 94.2 m / s. Determine the period of rotation of the wheel if the diameter is 300mm.

To determine the period of rotation of the used abrasive wheel, we use the formula: T = 2 * Π * R / V = Π * d / V.

The values of the variables: d is the diameter of the abrasive wheel (d = 300 mm = 0.3 m); V – circle speed (V = 94.2 m / s).

Let’s make a calculation: T = Π * d / V = 3.14 * 0.3 / 94.2 = 0.01 s.

Answer: The period of rotation of the abrasive wheel used is 0.01 s.
