1. What Is The Torque Equation?

The torque equation T = K × F × D calculates the torque required for screws and bolts, where T is torque, K is a dimensionless coefficient, F is the applied force, and D is the diameter.

2. How Does The Calculator Work?

The calculator uses the torque equation:

Where:

• \( T \) — Torque (Nm)
• \( K \) — Dimensionless coefficient
• \( F \) — Force (N)
• \( D \) — Diameter (m)

Explanation: The equation calculates the rotational force (torque) needed based on the coefficient, applied force, and diameter.

3. Importance Of Torque Calculation

Details: Accurate torque calculation is crucial for proper fastening, preventing under-tightening or over-tightening of screws and bolts in mechanical applications.

4. Using The Calculator

Tips: Enter the coefficient (K), force in Newtons (N), and diameter in meters (m). All values must be positive.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical range for coefficient K?
A: The coefficient K typically ranges from 0.15 to 0.3 depending on the material and lubrication conditions.

Q2: Why is torque important in screw fastening?
A: Proper torque ensures that screws are tightened to the correct tension, preventing loosening or damage to threads.

Q3: Can this equation be used for all types of screws?
A: This equation is generally applicable for standard screws and bolts, but specific applications may require adjustments.

Q4: What units should be used for diameter?
A: Diameter should be in meters (m) to maintain consistency with SI units for torque (Nm).

Q5: How does lubrication affect the coefficient K?
A: Lubrication typically reduces the coefficient K, resulting in less torque required for the same clamping force.
