1. What is Power Output?

Power output is the rate at which work is done or energy is transferred in rotational systems. It's calculated as the product of torque and angular velocity.

2. How Does the Calculator Work?

The calculator uses the power output formula:

Where:

• \( P \) — Power output (Watts)
• \( \tau \) — Torque (Newton-meters)
• \( \omega \) — Angular velocity (radians per second)

Explanation: This formula shows the direct relationship between rotational force (torque), speed of rotation, and the resulting power output.

3. Importance of Power Calculation

Details: Calculating power output is essential for designing mechanical systems, evaluating engine performance, and determining energy requirements in rotational applications.

4. Using the Calculator

Tips: Enter torque in N·m and angular velocity in rad/s. Both values must be positive numbers for accurate calculations.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between power and torque?
A: Torque is a rotational force, while power is the rate at which work is done (torque × angular velocity).

Q2: How do I convert RPM to rad/s?
A: Multiply RPM by 2π/60 (1 RPM = 0.10472 rad/s).

Q3: What are typical power outputs for engines?
A: Car engines typically range from 50-500 kW, while industrial motors can be much higher.

Q4: Can this formula be used for linear motion?
A: No, for linear motion use P = F × v (force × velocity).

Q5: Why is power output important in engineering?
A: It helps determine system efficiency, size components correctly, and ensure adequate energy supply for mechanical operations.
