Determine the period of rotation of the driving wheels of an electric locomotive with a diameter of 1.5 m at a speed of 36 km / h.
These tasks: D (diameter of the driving wheels of the electric locomotive) = 1.5 m; V (speed of movement of the electric locomotive) = 36 km / h (10 m / s).
The period of rotation of the driving wheels of the electric locomotive is determined by the formula: T = 2 * Π * r / V = Π * D / V.
Calculation: T = 3.14 * 1.5 / 10 = 0.471 s.
Answer: The driving wheels of the electric locomotive rotate with a period of 0.471 s.
