# Torsion Spring Torque Calculator, Formula, Torsion Spring Torque Calculation

## Torsion Spring Torque Calculator:

Enter the values of total angular displacement, D(rad) and torsion spring rating, TSR(N.m/rad) to generate the value of torsion spring torque, Tts(N.m).

 Enter Total Angular Displacement: rad Enter Torsion Spring Rating: N.m/rad Result – Torsion Spring Torque: N.m

## Torsion Spring Torque Formula:

Torsion spring torque measures the rotational force generated by a torsion spring when it is twisted.

Torsion spring torque, Tts(N.m) in Newton metre is calculated by the product of total angular displacement, D(rad) in radians and torsion spring rating, TSR(N.m/rad) in Newton metres per radians.

Tts(N.m) = torsion spring torque in Newton metres, N.m.

### Torsion Spring Torque Calculation:

1. Suppose a torsion spring in a mechanical clock is twisted through an angle of 0.5 radians. If the spring rate is 0.8 N.m/radian, calculate the torque exerted by the spring.

Tts(N.m) = 0.5 * 0.8

Tts(N.m) = 0.4N.m.

2. A garage door torsion spring is twisted to a deflection of 2 radians to lift the door. If the torsion spring torque required to balance and hold the door open is 10 N.m, what is the spring rate of the torsion spring?
