The motors of an electric locomotive when moving at a speed of 72 km / h consume a power of 600 kW.

The motors of an electric locomotive when moving at a speed of 72 km / h consume a power of 600 kW. What is the traction force of the electric locomotive?

Initial data: V (constant speed of movement) = 72 km / h (in SI system V = 20 m / s); N (the power of the motors of the electric locomotive in question) = 600 kW (600 * 10 ^ 3 W).

The traction force of the motors of the electric locomotive under consideration can be determined by the formula: F = N / V.

Let’s perform the calculation: F = 600 * 10 ^ 3/20 = 30 * 10 ^ 3 N (30 kN).

Answer: The motors of the electric locomotive in question must create a traction force of 30 kN.
