1. What is the Torque Formula?

The torque formula T = K × F × D calculates the torque required for bolt tightening, where T is torque (Nm), K is a dimensionless constant, F is force (N), and D is distance (m).

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( T \) — Torque (Nm)
• \( K \) — Dimensionless constant
• \( F \) — Force (N)
• \( D \) — Distance (m)

Explanation: The formula calculates the rotational force required to properly tighten bolts based on the friction coefficient, applied force, and distance from the pivot point.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for proper bolt tightening, preventing under-tightening (which can cause loosening) and over-tightening (which can damage threads or cause bolt failure).

4. Using the Calculator

Tips: Enter the dimensionless constant K, force in Newtons (N), and distance in meters (m). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical range for K values?
A: K values typically range from 0.1 to 0.3 for most bolt applications, depending on surface finish, lubrication, and thread type.

Q2: Why is proper torque important?
A: Proper torque ensures joint integrity, prevents leaks, maintains clamping force, and avoids damage to components.

Q3: How does lubrication affect torque calculations?
A: Lubrication reduces friction, which lowers the K value and requires less torque to achieve the same clamping force.

Q4: Can this formula be used for all bolt types?
A: While the basic formula applies to most bolts, specific applications may require adjustments for thread type, material, and environmental conditions.

Q5: What units should be used for accurate calculations?
A: Consistent SI units should be used - Newtons for force and meters for distance to get torque in Newton-meters (Nm).
