1. What is the Torque to Force Formula?

The torque to force formula calculates the linear force generated from torque applied to a bolt or fastener. This is essential in mechanical engineering for determining proper bolt tension and ensuring structural integrity.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( F \) — Force (N)
• \( T \) — Torque (Nm)
• \( K \) — Dimensionless coefficient (typically 0.2 for standard bolts)
• \( D \) — Bolt diameter (m)

Explanation: The formula converts rotational torque into linear force, accounting for friction and mechanical advantage through the coefficient K.

3. Importance of Force Calculation

Details: Accurate force calculation is crucial for proper bolt tensioning, preventing joint failure, ensuring safety, and maintaining structural integrity in mechanical assemblies.

4. Using the Calculator

Tips: Enter torque in Nm, coefficient value (typically 0.2 for standard applications), and bolt diameter in meters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical value for coefficient K?
A: For standard bolts, K is typically 0.2, but this can vary based on thread pitch, lubrication, and material properties.

Q2: Why is diameter measured in meters?
A: The formula requires SI units for consistency. Convert from millimeters by dividing by 1000 (e.g., 10mm = 0.01m).

Q3: Can this formula be used for all bolt types?
A: While the formula is generally applicable, specific bolt types may require adjusted coefficients. Consult engineering specifications for critical applications.

Q4: How accurate is this calculation?
A: Accuracy depends on the precision of the coefficient value. For critical applications, physical testing is recommended to verify calculations.

Q5: What affects the coefficient K value?
A: Thread friction, surface finish, lubrication, and material properties all influence the K value. Different applications may require different coefficients.
