1. What is a Torsion Spring Torque Calculator?

Definition: This calculator determines the torque produced by a torsion spring based on its spring constant and angular deflection.

Purpose: It helps engineers and designers calculate the rotational force exerted by torsion springs in mechanical systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \tau \) — Torque (Newton-meters, Nm)
• \( k \) — Spring constant (Nm/rad)
• \( \theta \) — Angular deflection (radians)

Explanation: The spring constant multiplied by the angular deflection gives the torque exerted by the spring.

3. Importance of Torsion Spring Calculations

Details: Accurate torque calculations ensure proper spring selection for applications like garage doors, clothespins, and various mechanical assemblies.

4. Using the Calculator

Tips: Enter the spring constant in Nm/rad and the angular deflection in radians. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical spring constant range?
A: Spring constants vary widely from 0.001 Nm/rad for small springs to 100+ Nm/rad for heavy-duty industrial springs.

Q2: How do I convert degrees to radians?
A: Multiply degrees by π/180 (approximately 0.01745). Our calculator requires input in radians.

Q3: Does this account for spring fatigue?
A: No, this calculates ideal torque. For long-term performance, consider fatigue life and safety factors.

Q4: What affects a spring's constant?
A: Material, wire diameter, coil diameter, and number of active coils primarily determine the spring constant.

Q5: Can I use this for helical torsion springs?
A: Yes, this formula applies to all torsion springs where torque is proportional to angular deflection.
