1. What is Torque?

Torque is a measure of the rotational force applied to an object. It represents how much force is acting on an object to cause it to rotate. The SI unit for torque is the newton-meter (N·m).

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( \tau \) — Torque (N·m)
• \( P \) — Power (W)
• \( \omega \) — Angular speed (rad/s)

Explanation: Torque is calculated by dividing the power by the angular speed. This relationship shows that for a given power, torque decreases as rotational speed increases.

3. Importance of Torque Calculation

Details: Torque calculation is essential in mechanical engineering, automotive design, and industrial applications. It helps determine the rotational force needed for motors, engines, and other rotating machinery.

4. Using the Calculator

Tips: Enter power in watts (W) and angular speed in radians per second (rad/s). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between torque and power?
A: Torque is a rotational force, while power is the rate at which work is done. Power equals torque multiplied by angular speed.

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 torque values for car engines?
A: Passenger car engines typically produce 100-400 N·m of torque, depending on engine size and type.

Q4: Why is torque important in motors?
A: Torque determines a motor's ability to overcome resistance and perform work. Higher torque means better ability to handle heavy loads.

Q5: How does gear ratio affect torque?
A: Gear reduction increases torque while decreasing speed, maintaining the same power (minus efficiency losses).
