1. What is the Torque To Force Formula?

The Torque To Force formula calculates the linear force generated from torque applied to a screw thread. This is essential in mechanical engineering for determining the clamping force or tension in threaded fasteners.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( F \) — Force (lb)
• \( T \) — Torque (lb-in)
• \( K \) — Torque coefficient (decimal)
• \( D \) — Diameter (in)

Explanation: The formula converts rotational torque into linear force by accounting for the screw diameter and friction coefficient.

3. Importance of Force Calculation

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

4. Using the Calculator

Tips: Enter torque in lb-in, torque coefficient as a decimal value, and diameter in inches. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical torque coefficient value?
A: Torque coefficients typically range from 0.15 to 0.25 for most threaded fasteners, but vary based on lubrication and surface conditions.

Q2: Why is diameter important in this calculation?
A: Diameter determines the lever arm length, directly affecting how torque translates to linear force.

Q3: Can this formula be used for metric units?
A: Yes, but ensure all units are consistent (e.g., N·m for torque and mm for diameter, with appropriate unit conversion).

Q4: What affects the torque coefficient value?
A: Surface finish, lubrication, thread pitch, and material properties all influence the torque coefficient.

Q5: How accurate is this calculation?
A: Accuracy depends on precise measurement of torque coefficient, which can vary significantly in practical applications.
