Enter the modulus of elasticity, angular deflection, length, width, and thickness of a torsion spring into the calculator to determine the torque.

Spiral Torsion Spring Formula

The following formula is used to calculate the torque provided by a spiral spring.

M = [ pi * E * b * t^3 * theta ] / [ 6 * L ]

  • Where E is the modulus of elasticity
  • b is the material width
  • t is the material thickness
  • theta is the angle of deflection
  • L is the length

Spiral Torsion Definition

Spiral torsion is the measure of torque of the moment about an axis caused by a helical spring and twisting force.
