1. What is the Torque to Tension Formula?

The torque to tension formula calculates the linear tension force (F) generated from applied torque (T), using the coefficient (K) and diameter (D) parameters. This calculation is essential in mechanical engineering applications involving bolted joints, fasteners, and rotational systems.

2. How Does the Calculator Work?

The calculator uses the torque to tension formula:

Where:

• \( F \) — Tension force (N)
• \( T \) — Applied torque (Nm)
• \( K \) — Coefficient (dimensionless)
• \( D \) — Diameter (m)

Explanation: The formula converts rotational torque into linear tension force, accounting for the mechanical advantage provided by the diameter and the specific coefficient factor.

3. Importance of Torque to Tension Calculation

Details: Accurate torque to tension conversion is crucial for proper fastener installation, preventing joint failure, ensuring structural integrity, and maintaining safety standards in mechanical assemblies.

4. Using the Calculator

Tips: Enter torque in Newton-meters (Nm), coefficient (dimensionless value), and diameter in meters (m). 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 0.15 to 0.25 for standard bolted joints, but varies based on thread type, lubrication, and material properties.

Q2: Why is diameter measurement important?
A: Diameter directly affects the mechanical advantage - larger diameters require less torque to achieve the same tension force.

Q3: When should this calculation be used?
A: This calculation is essential for proper bolt tightening, flange assembly, and any application where precise tension control is required from torque application.

Q4: Are there limitations to this formula?
A: The formula assumes ideal conditions and may need adjustment for friction variations, thread wear, lubrication changes, and non-standard geometries.

Q5: How accurate is this calculation?
A: Accuracy depends on precise measurement of all parameters. For critical applications, direct tension measurement or calibrated torque tools are recommended.
