Torsion Spring Torque Calculator


Calculating torsion spring torque is essential in various engineering and mechanical applications, where understanding the force and rotational movement of a torsion spring is crucial. This article provides a simple calculator tool to compute torsion spring torque efficiently.

How to Use

To utilize the torsion spring torque calculator, follow these steps:

  1. Enter the values of the spring constant (k) and the angle of deflection (θ) in their respective input fields.
  2. Click the “Calculate” button to obtain the torque exerted by the torsion spring.


The torque (τ) exerted by a torsion spring can be calculated using the formula:



  • τ is the torque (in units of force multiplied by distance, e.g., Newton-meters or pound-feet).
  • k is the spring constant (in units of force per unit angle, e.g., Newton-meters per radian or pound-inches per degree).
  • θ is the angle of deflection (in radians or degrees).

Example Solve

Suppose we have a torsion spring with a spring constant k=50 Nm/rad and an angle of deflection θ=30 degrees.

Using the formula:




So, the torque exerted by the torsion spring is approximately 26.18 Nm.
