1. What is the Torque to Force Formula?

The torque to force formula calculates the axial force generated from screw torque in mechanical systems. It provides a fundamental relationship between applied torque and the resulting linear force in screw thread applications.

2. How Does the Calculator Work?

The calculator uses the torque to force formula:

Where:

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

Explanation: The formula converts rotational torque into linear force, accounting for the mechanical advantage provided by the screw thread geometry.

3. Importance of Torque to Force Calculation

Details: Accurate force calculation is crucial for proper bolt tensioning, fastener design, mechanical assembly, and ensuring structural integrity in various engineering applications.

4. Using the Calculator

Tips: Enter torque in N·m, coefficient value, and diameter in meters. All values must be valid 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 threaded fasteners, depending on thread geometry and friction conditions.

Q2: How does lubrication affect the calculation?
A: Lubrication reduces friction, which affects the K coefficient. Proper lubrication can significantly increase the axial force generated for the same applied torque.

Q3: Can this formula be used for both metric and imperial units?
A: Yes, but all units must be consistent. Convert all measurements to the same system (SI or imperial) before calculation.

Q4: What factors influence the coefficient K?
A: Thread pitch, friction coefficients, material properties, surface finish, and lubrication all influence the K value.

Q5: Is this formula accurate for all screw types?
A: While generally applicable, specific screw types (acme threads, ball screws) may require modified formulas due to different efficiency characteristics.
