What is Torque?

Torque, often referred to as the moment of force, is a measure of the rotational force applied to an object. It is a vector quantity, meaning it has both magnitude and direction. The formula for torque (τ) can be expressed as:

τ = r × F

Where:

• τ = Torque
• r = Distance from the pivot point to the point of force application
• F = Force applied

Understanding torque is essential for analyzing rotational systems in various fields, including mechanics, structural engineering, and robotics.

How Does the Right Hand Rule Torque Work?

The right hand rule torque is a simple yet powerful mnemonic that helps visualize the direction of torque. To apply this rule, follow these steps:

1. Extend your right hand.
2. Point your fingers in the direction of the applied force.
3. Curl your fingers in the direction of the rotation caused by the force.
4. Your thumb will now point in the direction of the torque vector.

This method allows you to easily determine the direction of torque without complex calculations, making it an invaluable tool for students and professionals alike.

Where is the Right Hand Rule Torque Applied?

The right hand rule torque finds applications in various fields, including:
