The points of the grinding wheel, which makes one revolution in 0.5 s, move at a speed constant in absolute value.

The points of the grinding wheel, which makes one revolution in 0.5 s, move at a speed constant in absolute value. What is the speed of the points of the circle that are 0.1 m away from its axis?

Initial data: T (period of rotation of the taken grinding wheel) = 0.5 s; R (radius of rotation, removal of points of the grinding wheel from the axis of rotation) = 0.1 m.
The linear speed of the considered points of the grinding wheel can be calculated by the formula: V = 2 * Π * R / T.
Let’s perform the calculation: V = 2 * 3.14 * 0.1 / 0.5 = 1.256 m / s.
Answer: The linear speed of the points of the grinding wheel under consideration is 1.256 m / s.
