These tasks: ν (frequency with which the considered shaft rotates) = 300 rpm (5 rpm); d (shaft diameter) = 10 cm (0.1 m).
The linear speed of points on the surface of the considered shaft is calculated by the formula: V = 2 * Π * R * ν = Π * d * ν.
Calculation: V = 3.14 * 0.1 * 5 = 1.57 m / s.
Answer: Points on the surface of the shaft in question have a linear velocity of 1.57 m / s.
