Question

An automobile engine develops 100 kW when rotating at a speed of 1800 rev/min. What torque does it deliver

• A. 350 N-m
• B. 440 N-m
• C. 531 N-m
• D. 628 N-m

Answer 1

The correct option is C 531 N-m

$P=\tau \omega \Rightarrow \tau =\frac{100\times {10}^3}{2\pi \frac{1800}{60}}=531N-m$
