1. What is Linear Force From Screw Torque?

The linear force from screw torque calculation determines the axial force generated by a screw mechanism when torque is applied. This is essential in mechanical engineering applications involving screws, bolts, and lead screws.

2. How Does the Calculator Work?

The calculator uses the linear force formula:

Where:

• \( F \) — Linear force (N)
• \( T \) — Torque (Nm)
• \( \eta \) — Efficiency (dimensionless)
• \( L \) — Lead (m)

Explanation: The formula calculates the axial force produced by a screw mechanism based on the input torque, screw efficiency, and lead distance.

3. Importance of Linear Force Calculation

Details: Accurate linear force calculation is crucial for designing mechanical systems, determining load capacities, and ensuring proper screw/bolt selection for various applications.

4. Using the Calculator

Tips: Enter torque in Nm, efficiency as a dimensionless value (0-1), and lead in meters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is screw lead?
A: Screw lead is the linear distance the screw travels in one complete revolution (360° rotation).

Q2: What is typical screw efficiency?
A: Screw efficiency typically ranges from 0.3 to 0.9, depending on the screw type, material, and lubrication.

Q3: Can this formula be used for all screw types?
A: This formula applies to most screw mechanisms, but specific screw designs may require additional factors or modifications.

Q4: How does friction affect the calculation?
A: Friction is accounted for in the efficiency factor (η). Lower efficiency values indicate higher friction losses.

Q5: What units should I use for accurate results?
A: Use consistent SI units: torque in Newton-meters (Nm), lead in meters (m), and force will be calculated in Newtons (N).
