The speed of points on the working surface of an emery wheel with a diameter of 300 mm is 35 m. What is the period of circulation of the emery wheel?
To find the required period of circulation of the used emery wheel, we will use the formula: T = 2 * Π * R / V = d * Π / V.
The values of the variables: d is the diameter of the emery wheel (d = 300 mm = 0.3 m); V is the speed of points on the working surface (V = 35 m / s).
Let’s perform the calculation: T = d * Π / V = 0.3 * 3.14 / 35 = 0.027 s.
Answer: The period of circulation of the used emery wheel is 0.027 s.
