Task data: n (rated speed) = 2800 rpm; N (rated power of the motor in question) = 5 kW.
To determine the useful moment on the shaft of the engine under consideration, we use the formula: N (kW) = M (N * m) * n (rpm) / 9550 (coefficient), whence M = 9550 * N / m.
Let’s calculate: M = 9550 * 5/2800 = 17 N * m.
Answer: The useful moment on the shaft of the engine in question is 17 N * m.
