1. What is Torsion Spring Torque?

Torsion spring torque is the rotational force exerted by a torsion spring when it's twisted. It's calculated as the product of the spring constant (k) and the angular displacement (θ) from its rest position.

2. How Does the Calculator Work?

The calculator uses the torsion spring torque equation:

Where:

• \( \tau \) — Torque (N·m)
• \( k \) — Spring constant (N·m/rad)
• \( \theta \) — Angular displacement (rad)

Explanation: The torque is directly proportional to both the spring constant and the angle of twist.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for designing mechanical systems with torsion springs, ensuring proper function and safety in applications like garage doors, clothespins, and various mechanical assemblies.

4. Using the Calculator

Tips: Enter spring constant in N·m/rad and angular displacement in radians. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical spring constant for torsion springs?
A: Spring constants vary widely depending on application, ranging from 0.01 N·m/rad for small springs to 100+ N·m/rad for heavy-duty industrial springs.

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

Q3: What affects a torsion spring's constant?
A: Material properties, wire diameter, coil diameter, and number of active coils primarily determine the spring constant.

Q4: Is the torque linear throughout the spring's range?
A: Ideally yes, but in practice there may be slight non-linearities at extreme deflections.

Q5: How does temperature affect torsion spring torque?
A: Higher temperatures typically reduce torque output as the material becomes less stiff.
