1. What is the Torque Equation?

The torque equation T = K × F × D calculates the torque required for screws and fasteners, where T is torque (Nm), K is a dimensionless factor, F is force (N), and D is diameter (m).

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

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

Explanation: The equation calculates the rotational force required to properly tighten a screw or fastener based on material properties and dimensions.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for ensuring proper fastening, preventing damage to materials, and maintaining structural integrity in mechanical assemblies.

4. Using the Calculator

Tips: Enter the dimensionless factor K, force in Newtons, and diameter in meters. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical range for K values?
A: K values typically range from 0.1 to 0.3 for most screw applications, depending on material and lubrication.

Q2: Why is torque measurement important?
A: Proper torque ensures secure fastening without damaging threads or stripping screws, maintaining safety and reliability.

Q3: How does diameter affect torque requirements?
A: Larger diameters require more torque to achieve the same clamping force, as torque is directly proportional to diameter.

Q4: Are there different torque equations for different screw types?
A: While the basic T = KFD equation is universal, specific applications may use modified versions with additional factors.

Q5: Should torque values be adjusted for different materials?
A: Yes, different materials require different torque values to account for friction coefficients and material strength properties.
