Problem: A motor applies a constant torque of 50 Newton-meters to a wheel. The wheel rotates at a constant angular velocity of 10 radians per second. Calculate the power delivered by the motor. Step 1: Identify the given values. Torque (τ) = 50 Nm Angular Velocity (ω) = 10 rad/s Step 2: Recall the formula for rotational power. Power (P) = Torque (τ) × Angular Velocity (ω) Step 3: Substitute the values into the formula. P = 50 Nm × 10 rad/s Step 4: Calculate the result. P = 500 Watts Answer: The power delivered by the motor is 500 Watts.
