1. What is the Torque Formula?

The torque formula T = K × F × D calculates the torque required to achieve a specific clamping force in mechanical systems, where K is a dimensionless coefficient, F is the clamping force in Newtons, and D is the diameter in meters.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( T \) — Torque (Nm)
• \( K \) — Dimensionless coefficient
• \( F \) — Clamping force (N)
• \( D \) — Diameter (m)

Explanation: The formula calculates the rotational force needed to generate a specific clamping force based on the system's mechanical characteristics.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for proper fastener tension, preventing joint failure, ensuring safety, and maintaining mechanical integrity in various engineering applications.

4. Using the Calculator

Tips: Enter the coefficient value, clamping force in Newtons, and diameter in meters. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical range for coefficient K?
A: The coefficient K typically ranges from 0.1 to 0.3 depending on the thread type, lubrication, and surface conditions.

Q2: How does diameter affect torque requirements?
A: Larger diameters require more torque to achieve the same clamping force, as torque is directly proportional to diameter.

Q3: What units should be used for accurate calculations?
A: Use Newtons for force, meters for diameter, and the result will be in Newton-meters (Nm) for torque.

Q4: Are there limitations to this formula?
A: This formula provides an estimate and may need adjustment for specific materials, thread conditions, or dynamic loading situations.

Q5: How often should torque calculations be verified?
A: Torque calculations should be verified whenever there are changes in materials, lubrication, or operating conditions.
