An engine transmits a constant power of 15 kW to a shaft rotating at a steady angular speed of 300 rpm. The torque delivered by the engine to the shaft is:

  1. \( \frac{1200}{\pi}\text{ N}\cdot\text{m} \)
  2. \( \frac{1500}{\pi}\text{ N}\cdot\text{m} \)
  3. \( \frac{750}{\pi}\text{ N}\cdot\text{m} \)
  4. \( \frac{3000}{\pi}\text{ N}\cdot\text{m} \)

Correct answer · Option 2

\( \frac{1500}{\pi}\text{ N}\cdot\text{m} \)

Explanation

\( \omega = \frac{2\pi \times 300}{60} = 10\pi\text{ rad/s} \). Instantaneous power \( P = \tau \omega \implies \tau = \frac{P}{\omega} = \frac{15000}{10\pi} = \frac{1500}{\pi}\text{ N}\cdot\text{m} \).
