1. What is Torque?

Torque is a measure of the rotational force applied to an object. It represents the tendency of a force to rotate an object about an axis, fulcrum, or pivot. Torque is calculated as the product of force and the perpendicular distance from the axis of rotation.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( T \) — Torque (Newton-meters)
• \( F \) — Force applied (Newtons)
• \( r \) — Radius or distance from axis (meters)
• \( \theta \) — Angle between force vector and lever arm (degrees)

Explanation: The formula calculates the rotational force by multiplying the applied force by the distance from the pivot point and the sine of the angle between the force vector and the lever arm.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial in mechanical engineering, automotive applications, construction, and various industrial processes where rotational forces need to be precisely measured and controlled.

4. Using the Calculator

Tips: Enter force in Newtons, radius in meters, and angle in degrees. All values must be valid (force > 0, radius > 0, angle between 0-90 degrees).

5. Frequently Asked Questions (FAQ)

Q1: Why is the angle important in torque calculation?
A: The angle determines the effective component of the force that contributes to rotation. Only the perpendicular component of the force creates torque.

Q2: What are typical torque values in mechanical applications?
A: Torque values vary widely depending on the application, from small precision instruments requiring fractions of Nm to large industrial machinery requiring thousands of Nm.

Q3: How does torque relate to power in mechanical systems?
A: Power is the product of torque and angular velocity. Higher torque at a given speed results in greater power output.

Q4: What's the difference between static and dynamic torque?
A: Static torque is applied without motion, while dynamic torque involves rotational movement. Both are calculated using the same formula.

Q5: Can this calculator be used for imperial units?
A: This calculator is specifically designed for metric units. For imperial units (lb-ft), appropriate unit conversions would be needed.
